This schema declares XML elements for the 15 DC elements from the
|
|
http://purl.org/dc/elements/1.1/ namespace.
|
|
|
|
It defines a complexType SimpleLiteral which permits mixed content
|
|
and makes the xml:lang attribute available. It disallows child elements by
|
|
use of minOcccurs/maxOccurs.
|
|
|
|
However, this complexType does permit the derivation of other complexTypes
|
|
which would permit child elements.
|
|
|
|
All elements are declared as substitutable for the abstract element any,
|
|
which means that the default type for all elements is dc:SimpleLiteral.

This is the default type for all of the DC elements.
|
|
It permits text content only with optional
|
|
xml:lang attribute.
|
|
Text is allowed because mixed="true", but sub-elements
|
|
are disallowed because minOccurs="0" and maxOccurs="0"
|
|
are on the xs:any tag.
|
|
|
|
This complexType allows for restriction or extension permitting
|
|
child elements.
