  10        This component schema defintion defines global schema data type declarations\r
  11        for data elements defined in the LOMv1.0 base schema.  This component XSD\r
  12        defines the aggregation relationship among the LOM data elements.  These aggregation\r
  13        relationships enforce the LOMv1.0 base schema requirement that elements can only\r
  14        be present in a LOM XML instance as elements of the aggregate element to which they\r
  15        belong.\r
  16 \r
  17        Duplicate declarations are included as comments for completeness.  These declarations\r
  18        should remain commented out or they can be removed completely.\r

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