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
