         This component schema defintion defines global element declarations for
         each of the data elements defined in the LOMv1.0 base schema.  This component
         schema definition is used to check for the uniqueness of elements declared
         to be unique within their parent elements by the presence of the
         "uniqueElementName" attribute.  The XML Schema constraint "unique" is used
         to enforce uniqueness constraints.

         Duplicate declarations are included as comments for completeness.  These
         declarations should remain commented out or they can be removed completely.

         This file has been modified by the Knowledge Media Institute of the 
         University Koblenz-Landau (http://iwm.uni-koblenz.de). It contains the
         following changes:
         1) Instead of "unique/strict.xsd" the schema "unique/loose.xsd" is imported 
            because this reflects what is said in 1484.12.3-2005, page 35 (section C.1.3)
         2) In all component XSDs the schemaLocation attribute was amended to the 
            xs:import and xs:include statements. This enables the usage of the schemas
            with tools which don't deal well with missing schemaLocation informations.
