			<documentation>This type is deprecated with GML 3 and shall not be used. It is included for backwards compatibility with GML 2. Use 
			CurvePropertyType instead. A property that has a line string 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>

				<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>
