    Subject: ID attributes

    Almost all attributes with name="ID" are of type="xsd:ID" now.
    Exceptions: ID attributes of Parameter elements (in data types and wildcards) and some identifiers in font handling.

    Advantage: ID were supposed to be unique whereever possible from beginning on. Now your XML application can check that during validation, as they have to be unique by definition. We also have an advantage when we refer to one of them in an attribute of type="IDREF". XMLSpy shows available ID entries for convenience.
