Thanks for the update! I've tested the new version of the schema against the following XML Schema processors: Xerces (2.0.1), XML Spy 4.4, MSXML4 SP1 and SQC with the following results: XML Spy 4.4 -------------- No problems SQC ------ No problems. (You have to add the namespace declaration for the xml: prefix but that's not really related to XML Schema validation) MSXML4 SP1: ----------------- All the built-in simpleType definitions that derive from xs:anySimpleType have the following error: "Whitespace constraining facet is prohibited" This was commented on by Dare in a previous post to this list. Xerces 2.0.1 -------------- Xerces has four problems with the schema: [1] (1 of 43) Schema problem: Unknown base type 'xs:anySimpleType' for a type 'string' (For simpleType name="string") [2] (2 of 43) Schema problem: Facet 'whiteSpace' is not allowed by this type. (For simpleType name="string") Both these errors occur for all the simpleTypes that derive from xs:anySimpleType [3] For the complexType "attributeGroupRef" the following errors are reported: (40 of 43) Schema problem: Group's occurrence range is not a valid restriction of base group's occurrence range. (41 of 43) Schema problem: Error for type 'attributeGroupRef'. The particle of the type is not a valid restriction of the particle of the base. [4] For the complexType "groupRef" the following errors are reported: (42 of 43) Schema problem: Group's occurrence range is not a valid restriction of base group's occurrence range. (43 of 43) Schema problem: Error for type 'groupRef'. The particle of the type is not a valid restriction of the particle of the base. If you would analyze the above results with regards to the validation results I would say that the following would be the case: 1) Since Xerces is the only processor to report the errors [1], [3] and [4] above my guess would be that these are a bug in Xerces and can be reported as such. 2) The Xerces bug [2] above is reported by both Xerces and MSXML4 so this probably needs clarification from the WG. I'd appreciate any comments on the above issues. Cheers, /Eddie > > ht > > [1] http://www.w3.org/2001/05/xmlschema-errata.html > -- > Henry S.
