This schema is based on the W3C XML Schema schema for XML Schemas: Part 2: Datatypes
The definitions of the "magic" built-in datatypes have been removed
The components for defining derived simpleTypes are retained, but defined in a new namespace.

  DHS Changes:  
    2006-09-28 Changed schema location for http://www.w3.org/XML/1998/namespace 
      from ../../../../../xml/1998/namespace/xml.xsd (rule-based)
      to ../../../../../w3c-xml/1998/xml.xsd (special case)
      
	2006-09-22 Changed namespaces following NIEM conventions
		 1) targetnamespace	 http://niem.gov//niem/external/l/ogc-observation/draft-0.14.5/st/dhs-gmo/1.0.0
		 
    2006-09-18 versioned namespace (was "http://www.opengis.net/swe/st"),
    import local copy of xml.xsd
