* <documentation>A property that has a curve as its value domain can either be an appropriate geometry element encapsulated in an
* element of this type or an XLink reference to a remote geometry element (where remote includes geometry elements located elsewhere
* in the same document). Either the reference or the contained element must be given, but neither both nor none.</documentation>

* <annotation>
* <documentation>This attribute group includes the XLink attributes (see xlinks.xsd). XLink is used in GML to reference remote
* resources (including those elsewhere in the same document). A simple link element can be constructed by including a specific
* set of XLink attributes. The XML Linking Language (XLink) is currently a Proposed Recommendation of the World Wide Web Consortium.
* XLink allows elements to be inserted into XML documents so as to create sophisticated links between resources; such links can be used
* to reference remote properties. A simple link element can be used to implement pointer functionality, and this functionality has been built
* into various GML 3 elements by including the gml:AssociationAttributeGroup.</documentation>
