This schema is not normative, or even definitive. The prose copy in the XLink
1.1 recommendation (http://www.w3.org/TR/xlink11/) is definitive, although it should
not
differ from this file, except for the absence of these two initial
comments.
In keeping with the W3C's standard versioning policy, this schema document
will persist at http://www.w3.org/XML/2008/06/xlink.xsd. At the date of issue it
can also be
found at http://www.w3.org/1999/xlink.xsd. The schema document at that URI may
however change
in the future, in order to remain compatible with the latest version of XML Schema
itself, or
with the XLink namespace itself. In other words, if the XML Schema or XLink namespaces
change,
the version of this document at http://www.w3.org/1999/xlink.xsd will change accordingly;
the
version at http://www.w3.org/2008/06/xlink.xsd will not change.
This schema document provides attribute declarations and attribute group,
complex type and simple type definitions which can be used in the construction
of user schemas
to define the structure of particular linking constructs, e.g.
<xs:schema xmlns:xs="http://www.w3.org/2001/XMLSchema"
xmlns:xl="http://www.w3.org/1999/xlink">
<xs:import namespace="http://www.w3.org/1999/xlink"
location="http://www.w3.org/1999/xlink.xsd">
<xs:element name="mySimple">
<xs:complexType>
...
<xs:attributeGroup ref="xl:simpleAttrs"/>
...
</xs:complexType>
</xs:element>
