A Value Array is used for homogeneous arrays of primitive and aggregate values.The member values may be scalars, composites, arrays or lists. ValueArray has the samecontent model as CompositeValue, but the member values shall be homogeneous. The elementdeclaration contains a Schematron constraint which expresses this restriction precisely.Since the members are homogeneous, the gml:referenceSystem (uom, codeSpace) may be specifiedon the gml:ValueArray itself and inherited by all the members if desired.
Database handle for the object. It is of XML type ID, so is constrained to beunique in the XML document within which it occurs. An external identifier for the object inthe form of a URI may be constructed using standard XML and XPointer methods. This is doneby concatenating the URI for the document, a fragment separator, and the value of the idattribute.
