AGLSTERMS XML Schema XML Schema for http://www.agls.gov.au/agls/terms/ namespace This schema declares XML properties for the AGLS properties and AGLS encoding schemes from the http://www.agls.gov.au/agls/terms/ namespace. It reuses the complexType dc:SimpleLiteral, imported from the dc.xsd schema, which permits simple property content, and makes the xml:lang attribute available. This complexType permits the derivation of other complexTypes which would permit child elements. DC properties are declared as substitutable for the abstract property dc:any, and DC property refinements are defined as substitutable for the base properties which they refine. This means that the default type for all XML properties (i.e. all DC and AGLS properties) is dc:SimpleLiteral. Encoding schemes are defined as complexTypes which are restrictions of the dc:SimpleLiteral complexType. These complexTypes restrict values to an appropriates syntax or format using data typing, regular expressions, or enumerated lists. In order to specify one of these encodings an xsi:type attribute must be used in the instance document. Also, note that one shortcoming of this approach is that any type can be applied to any of the properties. There is no convenient way to restrict types to specific properties using this approach.
