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.

51            Text is allowed because mixed="true", but sub-elements
