Created by Tom Habing, thabing@uiuc.edu and Tim Cole, t-cole3@uiuc.edu XML Schema for the Dublin Core Qualifiers http://www.dublincore.org/documents/dcmes-qualifiers/ Refinements are defined as substitutionGroups for the base elements which they refine, imported from the dc1.1.xsd schema. Encodings are defined as complexTypes which are either restrictions or extensions of the SimpleLiteral, also imported from the dc1.1.xsd schema. In order to specify one of these encodings an xsi:type attribute must be used in the instance document. If one of these types is used, the content will be limited to text only, with an optional xml:lang attribute. Also, note that one shortcoming of this approach is that any type can be applied to any of the elements or refinements. There is no convenient way to restrict types to specific elements using this approach. Qualified DC XML Schema Tom Habing, thabing@uiuc.edu Tim Cole, t-cole3@uiuc.edu
