+==== To Do list for libcbor ====
+=== General ===
+* API review
+* Benchmark
+* Write examples
+** Simple decoder
+** Decoder to JSON
+** Windowed encoding/decoding (limited memory)
+
+=== Encoder ===
+* Write API docs
+* Add API for creating indeterminate-length arrays and maps
+* Add API for creating indeterminate-length strings
+* Add API for relaxing doubles to floats and to integers
+* Add length-checking of the sub-containers (#ifndef CBOR_ENCODER_NO_USER_CHECK)
+* Decide how to indicate number of bytes needed
+** Suggestion: return negative number from the functions
+
+=== Decoder ===
+* Write functions not yet implemented
+* Add API for stream-decoding strings
+* Add API for checking known tags and simple types
+* (unlikely) Add API for checking the pairing of a tag and the tagged type
+* Write tests for error conditions
+* Fuzzy-test the decoder

+ * \mainpage
+ * The TinyCBOR $(VERSION) library is a small CBOR encoder and decoder library,
+ * optimized for very fast operation with very small footprint. The main encoder
+ * and decoder functions do not allocate memory.
+ *
+ * TinyCBOR is divided into the following groups of functions and structures:
+ * - \ref CborGlobals
+ * - \ref CborEncoding
+ * - \ref CborParsing
+ * - \ref CborPretty
+ * - \ref CborToJson
+ */
+
+/**
+ * \file <cbor.h>
+ * The <cbor.h> is the main header in TinyCBOR and defines the constants used by most functions
+ * as well as the structures for encoding (CborEncoder) and decoding (CborValue).
+ *
+ * \sa <cborjson.h>
+ */
+

+ * \value CborSimpleType Type is one of CBOR Simple Types
+ * \value CborBooleanType Type is a boolean (true or false)
+ * \value CborNullType Type encodes a null
+ * \value CborUndefinedType Type encodes an undefined value
+ * \value CborHalfFloatType Type is an IEEE 754 half precision (16-bit) floating point type

+
+/**
+ * \enum CborKnownTags
+ * The CborKnownTags enum contains known tags specified in RFC 7049, for use by the application.
+ * TinyCBOR does not usually interpret the meaning of these tags and does not add them to the
+ * output stream, unless specifically instructed to do so in functions for that effect.
+ *
+ * \value CborDateTimeStringTag Text string contains a date-time encoded in RFC 3339 format, "YYYY-MM-DD hh:mm:ss+zzzz"
+ * \value CborUnixTime_tTag Number is a Unix time_t quantity, the number of seconds since 1970-01-01 midnight UTC
+ * \value CborPositiveBignumTag Item is a CBOR byte string encoding a positive integer of arbitrary precision
+ * \value CborNegativeBignumTag Item is a CBOR byte string encoding a negative integer of arbitrary precision
+ * \value CborDecimalTag Item is a CBOR array of two integers encoding a fixed-point decimal
+ * \value CborBigfloatTag Item is a bigfloat
+ * \value CborExpectedBase64urlTag Item is a CBOR byte string that is expected to be encoded as Base64Url
+ * \value CborExpectedBase64Tag Item is a CBOR byte string that is expected to be encoded as Base64
+ * \value CborExpectedBase16Tag Item is a CBOR byte string that is expected to be encoded as Base16 (also known as "hexdump")
+ * \value CborUriTag Item is a CBOR text string containing an URI (RFC 3986) or IRI (RFC 3987)
+ * \value CborBase64urlTag Item is a CBOR text string that was encoded as Base64Url
+ * \value CborBase64Tag Item is a CBOR text string that was encoded as Base64
+ * \value CborRegularExpressionTag Item is a CBOR text string containing a regular expression
+ * \value CborMimeMessageTag Item is a CBOR text string containing a MIME message (RFC 2045, 2046, 2047, 2822)
+ * \value CborSignatureTag Item contains CBOR-encoded data.
+ * This tag is also used as "file magic," marking a file as containing CBOR
+ */

+/**
+ * \typedef CborTag
+ * This typedef is an unsigned 64-bit integer. Known CBOR tags can be used from the CborKnownTags enum
+ * but the user application may use other tag values than the ones specified in RFC 7049.

+/**
+ * \defgroup CborEncoding Encoding to CBOR
+ * \brief Group of functions used to encode data to CBOR.
+ *
+ * CborEncoder is used to encode data into a CBOR stream. The outermost
+ * CborEncoder is initialized by calling cbor_encoder_init(), with the buffer
+ * where the CBOR stream will be stored. The outermost CborEncoder is usually
+ * used to encode exactly one item, most often an array or map. It is possible
+ * to encode more than one item, but care must then be taken on the decoder
+ * side to ensure the state is reset after each item was decoded.
+ *
+ * Nested CborEncoder objects are created using cbor_encoder_create_array() and
+ * cbor_encoder_create_map(), later closed with cbor_encoder_close_container()
+ * or cbor_encoder_close_container_checked(). The pairs of creation and closing
+ * must be exactly matched and their parameters are always the same.
+ *
+ * CborEncoder writes directly to the user-supplied buffer, without extra
+ * buffering. CborEncoder does not allocate memory and CborEncoder objects are
+ * usually created on the stack of the encoding functions.
+ *
+ * The example below initializes a CborEncoder object with a buffer and encodes
+ * a single integer.
+ *
+ * \code
+ * uint8_t buf[16];
+ * CborEncoder encoder;
+ * cbor_encoder_init(&encoder, &buf, sizeof(buf), 0);
+ * cbor_encode_int(&encoder, some_value);
+ * \endcode
+ *
+ * As explained before, usually the outermost CborEncoder object is used to add
+ * one array or map, which in turn contains multiple elements. The example
+ * below creates a CBOR map with one element: a key "foo" and a boolean value.
+ *
+ * \code
+ * uint8_t buf[16];
+ * CborEncoder encoder, mapEncoder;
+ * cbor_encoder_init(&encoder, &buf, sizeof(buf), 0);
+ * cbor_encoder_create_map(&encoder, &mapEncoder, 1);
+ * cbor_encode_text_stringz(&mapEncoder, "foo");
+ * cbor_encode_boolean(&mapEncoder, some_value);
+ * cbor_encoder_close_container(&encoder, &mapEncoder);
+ * \endcode
+ *
+ * <h3 class="groupheader">Error checking and buffer size</h2>
+ *
+ * All functions operating on CborEncoder return a condition of type CborError.
+ * If the encoding was successful, they return CborNoError. Some functions do
+ * extra checking on the input provided and may return some other error
+ * conditions (for example, cbor_encode_simple_value() checks that the type is
+ * of the correct type).
+ *
+ * In addition, all functions check whether the buffer has enough bytes to
+ * encode the item being appended. If that is not possible, they return
+ * CborErrorOutOfMemory.
+ *
+ * It is possible to continue with the encoding of data past the first function
+ * that returns CborErrorOutOfMemory. CborEncoder functions will not overrun
+ * the buffer, but will instead count how many more bytes are needed to
+ * complete the encoding. At the end, you can obtain that count by calling
+ * cbor_encoder_get_extra_bytes_needed().
+ *
+ * \section1 Finalizing the encoding
+ *
+ * Once all items have been appended and the containers have all been properly
+ * closed, the user-supplied buffer will contain the CBOR stream and may be
+ * immediately used. To obtain the size of the buffer, call
+ * cbor_encoder_get_buffer_size() with the original buffer pointer.
+ *
+ * The example below illustrates how one can encode an item with error checking
+ * and then pass on the buffer for network sending.
+ *
+ * \code
+ * uint8_t buf[16];
+ * CborError err;
+ * CborEncoder encoder, mapEncoder;
+ * cbor_encoder_init(&encoder, &buf, sizeof(buf), 0);
+ * err = cbor_encoder_create_map(&encoder, &mapEncoder, 1);
+ * if (!err)
+ * return err;
+ * err = cbor_encode_text_stringz(&mapEncoder, "foo");
+ * if (!err)
+ * return err;
+ * err = cbor_encode_boolean(&mapEncoder, some_value);
+ * if (!err)
+ * return err;
+ * err = cbor_encoder_close_container_checked(&encoder, &mapEncoder);
+ * if (!err)
+ * return err;
+ *
+ * size_t len = cbor_encoder_get_buffer_size(&encoder, buf);
+ * send_payload(buf, len);
+ * return CborNoError;
+ * \endcode
+ *
+ * Finally, the example below illustrates expands on the one above and also
+ * deals with dynamically growing the buffer if the initial allocation wasn't
+ * big enough. Note the two places where the error checking was replaced with
+ * an cbor_assertion, showing where the author assumes no error can occur.
+ *
+ * \code
+ * uint8_t *encode_string_array(const char **strings, int n, size_t *bufsize)
+ * {
+ * CborError err;
+ * CborEncoder encoder, arrayEncoder;
+ * size_t size = 256;
+ * uint8_t *buf = NULL;
+ *
+ * while (1) {
+ * int i;
+ * size_t more_bytes;
+ * uint8_t *nbuf = realloc(buf, size);
+ * if (nbuf == NULL)
+ * goto error;
+ * buf = nbuf;
+ *
+ * cbor_encoder_init(&encoder, &buf, size, 0);
+ * err = cbor_encoder_create_array(&encoder, &arrayEncoder, n);
+ * cbor_assert(err); // can't fail, the buffer is always big enough
+ *
+ * for (i = 0; i < n; ++i) {
+ * err = cbor_encode_text_stringz(&arrayEncoder, strings[i]);
+ * if (err && err != CborErrorOutOfMemory)
+ * goto error;
+ * }
+ *
+ * err = cbor_encoder_close_container_checked(&encoder, &arrayEncoder);
+ * cbor_assert(err); // shouldn't fail!
+ *
+ * more_bytes = cbor_encoder_get_extra_bytes_needed(encoder);
+ * if (more_size) {
+ * // buffer wasn't big enough, try again
+ * size += more_bytes;
+ * continue;
+ * }
+ *
+ * *bufsize = cbor_encoder_get_buffer_size(encoder, buf);
+ * return buf;
+ * }

+ * free(buf);
+ * return NULL;

+/**
+ * \defgroup CborParsing Parsing CBOR streams
+ * \brief Group of functions used to parse CBOR streams.
+ *
+ * TinyCBOR provides functions for pull-based stream parsing of a CBOR-encoded
+ * payload. The main data type for the parsing is a CborValue, which behaves
+ * like an iterator and can be used to extract the encoded data. It is first
+ * initialized with a call to cbor_parser_init() and is usually used to extract
+ * exactly one item, most often an array or map.
+ *
+ * Nested CborValue objects can be parsed using cbor_value_enter_container().
+ * Each call to cbor_value_enter_container() must be matched by a call to
+ * cbor_value_leave_container(), with the exact same parameters.
+ *
+ * The example below initializes a CborParser object, begins the parsing with a
+ * CborValue and decodes a single integer:
+ *
+ * \code
+ * int extract_int(const uint8_t *buffer, size_t len)
+ * {
+ * CborParser parser;
+ * CborValue value;
+ * int result;
+ * cbor_parser_init(buffer, len, 0, &buffer, &value);
+ * cbor_value_get_int(&value, &result);
+ * return result;
+ * }
+ * \endcode
+ *
+ * The code above does no error checking, which means it assumes the data comes
+ * from a source trusted to send one properly-encoded integer. The following
+ * example does the exact same operation, but includes error parsing and
+ * returns 0 on parsing failure:
+ *
+ * \code
+ * int extract_int(const uint8_t *buffer, size_t len)
+ * {
+ * CborParser parser;
+ * CborValue value;
+ * int result;
+ * if (cbor_parser_init(buffer, len, 0, &buffer, &value) != CborNoError)
+ * return 0;
+ * if (!cbor_value_is_integer(&value) ||
+ * cbor_value_get_int(&value, &result) != CborNoError)
+ * return 0;
+ * return result;
+ * }
+ * \endcode
+ *
+ * Note, in the example above, that one can't distinguish a parsing failure
+ * from an encoded value of zero. Reporting a parsing error is left as an
+ * exercise to the reader.
+ *
+ * The code above does not execute a range-check either: it is possible that
+ * the value decoded from the CBOR stream encodes a number larger than what can
+ * be represented in a variable of type \c{int}. If detecting that case is
+ * important, the code should call cbor_value_get_int_checked() instead.
+ *
+ * <h3 class="groupheader">Memory and parsing constraints</h3>
+ *
+ * TinyCBOR is designed to run with little memory and with minimal overhead.
+ * Except where otherwise noted, the parser functions always run on constant
+ * time (O(1)), do not recurse and never allocate memory (thus, stack usage is
+ * bounded and is O(1)).
+ *
+ * <h3 class="groupheader">Error handling and preconditions</h3>
+ *
+ * All functions operating on a CborValue return a CborError condition, with
+ * CborNoError standing for the normal situation in which no parsing error
+ * occurred. All functions may return parsing errors in case the stream cannot
+ * be decoded properly, be it due to corrupted data or due to reaching the end
+ * of the input buffer.
+ *
+ * Error conditions must not be ignored. All decoder functions have undefined
+ * behavior if called after an error has been reported, and may crash.
+ *
+ * Some functions are also documented to have preconditions, like
+ * cbor_value_get_int() requiring that the input be an integral value.
+ * Violation of preconditions also results in undefined behavior and the
+ * program may crash.

+ * \defgroup CborPretty Converting CBOR to text
+ * \brief Group of functions used to convert CBOR to text form.
+ *
+ * This group contains two functions that are can be used to convert one
+ * CborValue object to a text representation. This module attempts to follow
+ * the recommendations from RFC 7049 section 6 "Diagnostic Notation", though it
+ * has a few differences. They are noted below.
+ *
+ * TinyCBOR does not provide a way to convert from the text representation back
+ * to encoded form. To produce a text form meant to be parsed, CborToJson is
+ * recommended instead.
+ *
+ * Either of the functions in this section will attempt to convert exactly one
+ * CborValue object to text. Those functions may return any error documented
+ * for the functions for CborParsing. In addition, if the C standard library
+ * stream functions return with error, the text conversion will return with
+ * error CborErrorIO.
+ *
+ * These functions also perform UTF-8 validation in CBOR text strings. If they
+ * encounter a sequence of bytes that not permitted in UTF-8, they will return
+ * CborErrorInvalidUtf8TextString. That includes encoding of surrogate points
+ * in UTF-8.
+ *
+ * \warning The output type produced by these functions is not guaranteed to
+ * remain stable. A future update of TinyCBOR may produce different output for
+ * the same input and parsers may be unable to handle them.
+ *
+ * \sa CborParsing, CborToJson, cbor_parser_init()
+ */
+
+/**
+ * \addtogroup CborPretty
+ * @{
+ * <h2 class="groupheader">Text format</h2>
+ *
+ * As described in RFC 7049 section 6 "Diagnostic Notation", the format is
+ * largely borrowed from JSON, but modified to suit CBOR's different data
+ * types. TinyCBOR makes further modifications to distinguish different, but
+ * similar values.
+ *
+ * CBOR values are currently encoded as follows:
+ * \par Integrals (unsigned and negative)
+ * Base-10 (decimal) text representation of the value
+ * \par Byte strings:
+ * <tt>"h'"</tt> followed by the Base16 (hex) representation of the binary data, followed by an ending quote (')
+ * \par Text strings:
+ * C-style escaped string in quotes, with C11/C++11 escaping of Unicode codepoints above U+007F.
+ * \par Tags:
+ * Tag value, with the tagged value in parentheses. No special encoding of the tagged value is performed.
+ * \par Simple types:
+ * <tt>"simple(nn)"</tt> where \c nn is the simple value
+ * \par Null:
+ * \c null
+ * \par Undefined:
+ * \c undefined
+ * \par Booleans:
+ * \c true or \c false
+ * \par Floating point:
+ * If NaN or infinite, the actual words \c NaN or \c infinite.
+ * Otherwise, the decimal representation with as many digits as necessary to ensure no loss of information.
+ * By default, float values are suffixed by "f" and half-float values suffixed by "f16" (doubles have no suffix).
+ * If the CborPrettyNumericEncodingIndicators flag is active, the values instead are encoded following the
+ * Section 6 recommended encoding indicators: float values are suffixed with "_2" and half-float with "_1".
+ * A dot is always present.
+ * \par Arrays:
+ * Comma-separated list of elements, enclosed in square brackets ("[" and "]").
+ * \par Maps:
+ * Comma-separated list of key-value pairs, with the key and value separated
+ * by a colon (":"), enclosed in curly braces ("{" and "}").
+ *
+ * The CborPrettyFlags enumerator contains flags to control some aspects of the
+ * encoding:
+ * \par String fragmentation
+ * When the CborPrettyShowStringFragments option is active, text and byte
+ * strings that are transmitted in fragments are shown instead inside
+ * parentheses ("(" and ")") with no preceding number and each fragment is
+ * displayed individually. If a tag precedes the string, then the output
+ * will contain a double set of parentheses. If the option is not active,
+ * the fragments are merged together and the display will not show any
+ * difference from a string transmitted with determinate length.
+ * \par Encoding indicators
+ * Numbers and lengths in CBOR can be encoded in multiple representations.
+ * If the CborPrettyIndicateOverlongNumbers option is active, numbers
+ * and lengths that are transmitted in a longer encoding than necessary
+ * will be indicated, by appending an underscore ("_") to either the
+ * number or the opening bracket or brace, followed by a number
+ * indicating the CBOR additional information: 0 for 1 byte, 1 for 2
+ * bytes, 2 for 4 bytes and 3 for 8 bytes.
+ * If the CborPrettyIndicateIndetermineLength option is active, maps,
+ * arrays and strings encoded with indeterminate length will be marked by
+ * an underscore after the opening bracket or brace or the string (if not
+ * showing fragments), without a number after it.
+ */
+
+/**
+ * \enum CborPrettyFlags
+ * The CborPrettyFlags enum contains flags that control the conversion of CBOR to text format.
+ *
+ * \value CborPrettyNumericEncodingIndicators Use numeric encoding indicators instead of textual for float and half-float.
+ * \value CborPrettyTextualEncodingIndicators Use textual encoding indicators for float ("f") and half-float ("f16").
+ * \value CborPrettyIndicateIndetermineLength Indicate when a map or array has indeterminate length.
+ * \value CborPrettyIndicateOverlongNumbers Indicate when a number or length was encoded with more bytes than needed.
+ * \value CborPrettyShowStringFragments If the byte or text string is transmitted in chunks, show each individually.
+ * \value CborPrettyMergeStringFragment Merge all chunked byte or text strings and display them in a single entry.
+ * \value CborPrettyDefaultFlags Default conversion flags.

+ * \defgroup CborToJson Converting CBOR to JSON
+ * \brief Group of functions used to convert CBOR to JSON.
+ *
+ * This group contains two functions that are can be used to convert one
+ * CborValue object to an equivalent JSON representation. This module attempts
+ * to follow the recommendations from RFC 7049 section 4.1 "Converting from
+ * CBOR to JSON", though it has a few differences. They are noted below.
+ *
+ * These functions produce a "minified" JSON output, with no spacing,
+ * indentation or line breaks. If those are necessary, they need to be applied
+ * in a post-processing phase.
+ *
+ * Note that JSON cannot support all CBOR types with fidelity, so the
+ * conversion is usually lossy. For that reason, TinyCBOR supports adding a set
+ * of metadata JSON values that can be used by a JSON-to-CBOR converter to
+ * restore the original data types.
+ *
+ * The TinyCBOR library does not provide a way to convert from JSON
+ * representation back to encoded form. However, it provides a tool called
+ * \c json2cbor which can be used for that purpose. That tool supports the
+ * metadata format that these functions may produce.
+ *
+ * Either of the functions in this section will attempt to convert exactly one
+ * CborValue object to JSON. Those functions may return any error documented
+ * for the functions for CborParsing. In addition, if the C standard library
+ * stream functions return with error, the text conversion will return with
+ * error CborErrorIO.
+ *
+ * These functions also perform UTF-8 validation in CBOR text strings. If they
+ * encounter a sequence of bytes that not permitted in UTF-8, they will return
+ * CborErrorInvalidUtf8TextString. That includes encoding of surrogate points
+ * in UTF-8.
+ *
+ * \warning The metadata produced by these functions is not guaranteed to
+ * remain stable. A future update of TinyCBOR may produce different output for
+ * the same input and parsers may be unable to handle them.
+ *
+ * \sa CborParsing, CborPretty, cbor_parser_init()
+ */
+
+/**
+ * \addtogroup CborToJson
+ * @{
+ * <h2 class="groupheader">Conversion limitations</h2>
+ *
+ * When converting from CBOR to JSON, there may be information loss. This
+ * section lists the possible scenarios.
+ *
+ * \par Number precision:
+ * ALL JSON numbers, due to its JavaScript heritage, are IEEE 754
+ * double-precision floating point. This means JSON is not capable of
+ * representing integers numbers outside the range [-(2<sup>53</sup>)+1,
+ * 2<sup>53</sup>-1] and is not capable of representing NaN or infinite. If the
+ * CBOR data contains a number outside the valid range, the conversion will
+ * lose precision. If the input was NaN or infinite, the result of the
+ * conversion will be "null". In addition, the distinction between half-,
+ * single- and double-precision is lost.
+ *
+ * \par
+ * If enabled, the original value and original type are stored in the metadata.
+ *
+ * \par Non-native types:
+ * CBOR's type system is richer than JSON's, which means some data values
+ * cannot be represented when converted to JSON. The conversion silently turns
+ * them into strings: CBOR simple types become "simple(nn)" where \c nn is the
+ * simple type's value, with the exception of CBOR undefined, which becomes
+ * "undefined", while CBOR byte strings are converted to an Base16, Base64, or
+ * Base64url encoding
+ *
+ * \par
+ * If enabled, the original type is stored in the metadata.
+ *
+ * \par Presence of tags:
+ * JSON has no support for tagged values, so by default tags are dropped when
+ * converting to JSON. However, if the CborConvertObeyByteStringTags option is
+ * active (default), then certain known tags are honored and are used to format
+ * the conversion of the tagged byte string to JSON.
+ *
+ * \par
+ * If the CborConvertTagsToObjects option is active, then the tag and the
+ * tagged value are converted to to a JSON object. Otherwise, if enabled, the
+ * last (innermost) tag is stored in the metadata.
+ *
+ * \par Non-string keys in maps:
+ * JSON requires all Object keys to be strings, while CBOR does not. By
+ * default, if a non-string key is found, the conversion fails with error
+ * CborErrorJsonObjectKeyNotString. If the CborConvertStringifyMapKeys option
+ * is active, then the conversion attempts to create a string representation
+ * using CborPretty. Note that the \c json2cbor tool is not able to parse this
+ * back to the original form.
+ *
+ * \par Duplicate keys in maps:
+ * Neither JSON nor CBOR allow duplicated keys, but current TinyCBOR does not
+ * validate that this is the case. If there are duplicated keys in the input,
+ * they will be repeated in the output, which may JSON tools may flag as
+ * invalid. In addition to that, if the CborConvertStringifyMapKeys option is
+ * active, it is possible that a non-string key in a CBOR map will be converted
+ * to a string form that is identical to another key.
+ *
+ * \par
+ * When metadata support is active, the conversion will add extra key-value
+ * pairs to the JSON output so it can store the metadata. It is possible that
+ * the keys for the metadata clash with existing keys in the JSON map.

+/**
+ * \enum CborValidationFlags
+ * The CborValidationFlags enum contains flags that control the validation of a
+ * CBOR stream.
+ *
+ * \value CborValidateBasic Validates only the syntax correctedness of the stream.
+ * \value CborValidateCanonical Validates that the stream is in canonical format, according to
+ * RFC 7049 section 3.9.
+ * \value CborValidateStrictMode Performs strict validation, according to RFC 7049 section 3.10.
+ * \value CborValidateStrictest Attempt to perform the strictest validation we know of.
+ *
+ * \value CborValidateShortestIntegrals (Canonical) Validate that integral numbers and lengths are
+ * enconded in their shortest form possible.
+ * \value CborValidateShortestFloatingPoint (Canonical) Validate that floating-point numbers are encoded
+ * in their shortest form possible.
+ * \value CborValidateShortestNumbers (Canonical) Validate both integrals and floating-point numbers
+ * are in their shortest form possible.
+ * \value CborValidateNoIndeterminateLength (Canonical) Validate that no string, array or map uses
+ * indeterminate length encoding.
+ * \value CborValidateMapIsSorted (Canonical & Strict mode) Validate that map keys appear in
+ * sorted order.
+ * \value CborValidateMapKeysAreUnique (Strict mode) Validate that map keys are unique.
+ * \value CborValidateTagUse (Strict mode) Validate that known tags are used with the
+ * correct types. This does not validate that the content of
+ * those types is syntactically correct.
+ * \value CborValidateUtf8 (Strict mode) Validate that text strings are appropriately
+ * encoded in UTF-8.
+ * \value CborValidateMapKeysAreString Validate that all map keys are text strings.
+ * \value CborValidateNoUndefined Validate that no elements of type "undefined" are present.
+ * \value CborValidateNoTags Validate that no tags are used.
+ * \value CborValidateFiniteFloatingPoint Validate that all floating point numbers are finite (no NaN or
+ * infinities are allowed).
+ * \value CborValidateCompleteData Validate that the stream is complete and there is no more data
+ * in the buffer.
+ * \value CborValidateNoUnknownSimpleTypesSA Validate that all Standards Action simple types are registered
+ * with IANA.
+ * \value CborValidateNoUnknownSimpleTypes Validate that all simple types used are registered with IANA.
+ * \value CborValidateNoUnknownTagsSA Validate that all Standard Actions tags are registered with IANA.
+ * \value CborValidateNoUnknownTagsSR Validate that all Standard Actions and Specification Required tags
+ * are registered with IANA (see below for limitations).
+ * \value CborValidateNoUnkonwnTags Validate that all tags are registered with IANA
+ * (see below for limitations).
+ *
+ * \par Simple type registry
+ * The CBOR specification requires that registration for use of the first 19
+ * simple types must be done by way of Standards Action. The rest of the simple
+ * types only require a specification. The official list can be obtained from
+ * https://www.iana.org/assignments/cbor-simple-values/cbor-simple-values.xhtml.
+ *
+ * \par
+ * There are no registered simple types recognized by this release of TinyCBOR
+ * (beyond those defined by RFC 7049).
+ *
+ * \par Tag registry
+ * The CBOR specification requires that registration for use of the first 23
+ * tags must be done by way of Standards Action. The next up to tag 255 only
+ * require a specification. Finally, all other tags can be registered on a
+ * first-come-first-serve basis. The official list can be ontained from
+ * https://www.iana.org/assignments/cbor-tags/cbor-tags.xhtml.
+ *
+ * \par
+ * Given the variability of this list, TinyCBOR cannot recognize all tags
+ * registered with IANA. Instead, the implementation only recognizes tags
+ * that are backed by an RFC.
+ *
+ * \par
+ * These are the tags known to the current TinyCBOR release:
