The test is question is: contributor="Sun" set="Notation" group="name00101m2" test="name00101m2" and the test declares: <xsd:complexType name="Picture"> <xsd:attribute name="type"> <xsd:simpleType> <xsd:restriction base="xsd:NOTATION"> <xsd:enumeration value="jpeg"/> </xsd:restriction> </xsd:simpleType> </xsd:attribute> </xsd:complexType> where the schema contains no NOTATION with the name jpeg. One interpretation says the schema is invalid; the enumeration value must be in the value space of the base type, and the value space of NOTATION is the set of NOTATIONs declared in the "current schema". Another interpretation is that a reference to a missing component is not an error (and does not invalidate the schema) unless and until the component is needed to validate an instance. I think a WG ruling is needed on this one. The test is catalogued as invalid. 16996 1 paul 2007-10-02 19:55:22 +0000 I can tell you what *MY* interpretation is: the schema is invalid, for the first reason you state. If the spec is, indeed, unclear that this schema is invalid then it needs to be corrected. 18555 2 David_E3 2008-01-25 19:13:26 +0000 The WG agrees with the first interpretation, i.e.: the schema is invalid; the enumeration value must be in the value space of the base type, and the value space of NOTATION is the set of NOTATIONs declared in the "current schema". Note that the test could be properly catalogued as "valid" if the the following declaration were included in the schema: <xs:notation name="jpeg" public="image/jpeg" system="viewer.exe"/>
