  HREF="http://www.mozilla.org/NPL/NPL-1_1Final.html">Mozilla Public
  License Version 1.1</A>.  Alternatively you may use expat under the <A

  alternative license.</P>
  
  <P>Expat is an <A
  HREF="http://www.w3.org/TR/1998/REC-xml-19980210">XML 1.0</A> parser
  written in C. It aims to be fully conforming.  It is currently not a
  validating XML processor.  The current production version of expat can
  be downloaded from <A href = "ftp://ftp.jclark.com/pub/xml/expat.zip"
  >ftp://ftp.jclark.com/pub/xml/expat.zip</A>.</P>
  
  <P>The directory <SAMP>xmltok</SAMP> contains a low-level library for
  tokenizing XML.  The interface is documented in
  <SAMP>xmltok/xmltok.h</SAMP>.</P>
  
  <P>The directory <SAMP>xmlparse</SAMP> contains an XML parser library
  which is built on top of the <SAMP>xmltok</SAMP> library.  The
  interface is documented in <SAMP>xmlparse/xmlparse.h</SAMP>.  The
  directory <SAMP>sample</SAMP> contains a simple example program using
  this interface; <SAMP>sample/build.bat</SAMP> is a batch file to build
  the example using Visual C++.</P>
  
  <P>The directory <SAMP>xmlwf</SAMP> contains the <SAMP>xmlwf</SAMP>
  application, which uses the <SAMP>xmlparse</SAMP> library. The
  arguments to <SAMP>xmlwf</SAMP> are one or more files which are each
  to be checked for well-formedness. An option <SAMP>-d
  <VAR>dir</VAR></SAMP> can be specified; for each well-formed input
  file the corresponding <A
  href="http://www.jclark.com/xml/canonxml.html">canonical XML</A> will
  be written to <SAMP>dir/<VAR>f</VAR></SAMP>, where
  <SAMP><VAR>f</VAR></SAMP> is the filename (without any path) of the
  input file.  A <CODE>-x</CODE> option will cause references to
  external general entities to be processed.  A <CODE>-s</CODE> option
  will make documents that are not standalone cause an error (a document
  is considered standalone if either it is intrinsically standalone
  because it has no external subset and no references to parameter
  entities in the internal subset or it is declared as standalone in the
  XML declaration).</P>
  
  <P>The <SAMP>bin</SAMP> directory contains Win32 executables.  The
  <SAMP>lib</SAMP> directory contains Win32 import libraries.</P>
  
  <P>Answers to some frequently asked questions about expat can be found
  in the <A HREF="http://www.jclark.com/xml/expatfaq.html">expat
  FAQ</A>.</P>

  The map[b] member gives information about byte sequences
  whose first byte is b.
  If map[b] is c where c is >= 0, then b by itself encodes the Unicode scalar value c.
  If map[b] is -1, then the byte sequence is malformed.
  If map[b] is -n, where n >= 2, then b is the first byte of an n-byte
  sequence that encodes a single Unicode scalar value.
  The data member will be passed as the first argument to the convert function.
  The convert function is used to convert multibyte sequences;
  s will point to a n-byte sequence where map[(unsigned char)*s] == -n.
  The convert function must return the Unicode scalar value
  represented by this byte sequence or -1 if the byte sequence is malformed.
  The convert function may be null if the encoding is a single-byte encoding,

  using this mechanism.
  
  1. Every ASCII character that can appear in a well-formed XML document,
  other than the characters
  
    $@\^`{}~
  
  must be represented by a single byte, and that byte must be the
  same byte that represents that character in ASCII.
  
  2. No character may require more than 4 bytes to encode.
  
  3. All characters encoded must have Unicode scalar values <= 0xFFFF,
  (ie characters that would be encoded by surrogates in UTF-16
  are  not allowed).  Note that this restriction doesn't apply to
  the built-in support for UTF-8 and UTF-16.
  
  4. No Unicode character may be encoded by more than one distinct sequence
  of bytes. */
