This component schema defines attribute group declarations for LOM data
elements defined in the LOMv1.0 base schema to support schema-based
validation of the uniqueness constraints with a LOM XML instance by
introducing the attribute "uniqueElementName" for each LOM data element
that appears with a multiplicity of at most one.
NOTE: For most applications, enforcing the uniqueness constraints using the
unique/strict.xsd component XSD is desirable. Although adding the attribute
"uniqueElementName" is undesirable, it is unlikely to cause problems.
Duplicate declarations are included as comments for completeness. These
declarations should remain commented out or they can be removed completely.
