DCMES 1.1 XML Schema XML Schema for http://purl.org/dc/elements/1.1/ namespace Created 2008-02-11 Created by Tim Cole (t-cole3@uiuc.edu) Tom Habing (thabing@uiuc.edu) Jane Hunter (jane@dstc.edu.au) Pete Johnston (p.johnston@ukoln.ac.uk), Carl Lagoze (lagoze@cs.cornell.edu) 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. This group is included as a convenience for schema authors who need to refer to all the elements in the http://purl.org/dc/elements/1.1/ namespace. This complexType is included as a convenience for schema authors who need to define a root or container element for all of the DC elements.
