		<xs:documentation> Generic (user defined) attributes may be used to represent attributes which are not covered explicitly by
			the CityGML schema. Generic attributes must be used with care; they shall only be used if there is no appropiate attribute
			available in the overall CityGML schema. Oherwise, problems concerning semantic interoperability may arise. A generic
			attribute has a name and a value, which has further subclasses (IntAttrribute, StringAttribute, ...). </xs:documentation>
