23: This schema declares XML elements for the 15 DC elements from the
24: http://purl.org/dc/elements/1.1/ namespace.
25:
26: It defines a complexType SimpleLiteral which permits mixed content
27: and makes the xml:lang attribute available. It disallows child elements by
28: use of minOcccurs/maxOccurs.
29:
30: However, this complexType does permit the derivation of other complexTypes
31: which would permit child elements.
32:
33: All elements are declared as substitutable for the abstract element any,
34: which means that the default type for all elements is dc:SimpleLiteral.
