Imported schema xlink.xsd

Namespace

Annotations

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">

Attempting to install the relevant ISO 2- and 3-letter
         codes as the enumerated possible values is probably never
         going to be a realistic possibility.  See
         RFC 3066 at http://www.ietf.org/rfc/rfc3066.txt and the IANA registry
         at http://www.iana.org/assignments/lang-tag-apps.htm for
         further information.

         The union allows for the 'un-declaration' of xml:lang with
         the empty string.

Note that the elements referenced in the content model are all abstract.
The intention is that by simply declaring elements with these as their
