XMLSchema-instance and XMLSchema - need sources
Hi all,
By now I'm describing SOAP in my thesis but somehow can I not find good
information about these namespace declarations.
xmlns:xsi="http://www.w3.org/1999/XMLSchema-instance"
xmlns:xsd="http://www.w3.org/1999/XMLSchema">
Usually they are placed after the envelope declaration like this
<?xml version="1.0" encoding="UTF-8"?>
<SOAP-ENV:Envelope
xmlnx:SOAP-ENV="http://schemas.xmlsoap.org/soap/envelope/"
xmlns:xsi="http://www.w3.org/1999/XMLSchema-instance"
xmlns:xsd="http://www.w3.org/1999/XMLSchema">
...
</SOAP-ENV:Envelope>
As far as I could find out the
xmlns:xsi="http://www.w3.org/1999/XMLSchema-instance" is for using
xsi:type in the SOAP message and
xmlns:xsd="http://www.w3.org/1999/XMLSchema"> is used as value for the
xsi:type e.g. xsd:string
But I need more information about what they exactly do and what is the
difference between them and
xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" and
xmlns:xsd="http://www.w3.org/2001/XMLSchema"> ? (1999 vs 2001)
Can someone recommend me other detailed sources than W3C sources? Maybe
a good book?
Thanks a lot
Houman

Glue and Axis, which one is better
Posted by Jinghua Gu <eg...@cisco.com>.
Hi All,
Somebody said that Glue is 10 times faster than AXIS. Do you have
any comparison to share?
Thx,
Emily

Hi Anne,
Thank a lot. It was very helpful. Now I know how to describe it. :o)

Houman,
The 1999 XML Schema namespaces represent a draft version of the XML
Schema
specifications. The 2001 XML Schema namespaces represent the final W3C
XML
Schema Recommendation. You can also find numerous references to the 2000
XML
Schema namespace draft version (http://www.w3.org/2000/10/XMLSchema).
You might find the XML Schema Primer helpful in understanding XML
Schema:
http://www.w3.org/TR/xmlschema-0/.
The elements and attributes in the xsd: namespace (e.g., <element
name="foo"
type="string">) are used to define schemas. The xsd: elements and
attributes
aren't designed to be used within a document instance. (You use the
element
<foo> within your document, but you generally don't include the
definition
of that element within the document. Instead you refer to the schema
that
defines <foo>.) The xsi: namespace defines four attributes that you can
use
within your instance document to refer to additional schema information
(used primarily for validation). The xsi: attributes are xsi:type,
xsi:nil,
xsi:schemaLocation, and xsi:noNamespaceSchemaLocation. (See
http://www.w3.org/TR/2001/REC-xmlschema-1-20010502/#Instance_Document_Co
nstr
uctions)
The xsi: attribute you see most often in SOAP is the xsi:type attribute.
This attribute allows you to explicitly assert the type of an element in
an
XML document. The value of the xsi:type attribute is a QNAME that
specifies
the element type. It can refer to an XML Schema built-in type, e.g.:
<foo xsi:type="xsd:string">bar</foo>
or to a type that you've defined, e.g.:
<foo xsi:type="myxsd:myType">bar</foo>
where myType refers to a type defined in the myxsd schema).
See section 4.3 (http://www.w3.org/TR/xmlschema-0/#UseDerivInInstDocs)
in
the Schema Primer for a further description.
Best regards,
Anne
