   <xs:annotation>
       <xs:documentation>This component XSD requires schema components from other 
       schemas that are defined in other namespaces.  These statements import the 
       appropriate components. The xsi:schemaLocation attribute is used to specify 
       the location of the file that contains the schema that defines the namespace.  
       The xsi:schemaLocation attribute is optional and is ommitted.  By definition of 
       the composite schemas the appropriate namespaces and related files where those
       namespaces are defined are brought into scope.  Some XML parsers may require 
       these import statements to contain the optional xsi:schemaLocation attribute.</xs:documentation>
