There are known issues regarding content model restriction checking in
MSXML 4.0 which will be addressed in the future version (MSXML 6.0). I
am listing results for the sample schemas below.

Example1/2/3: known issue, fixed in future release.

** some more tests **

Example4: MSXML fails this since it is an invalid restriction.
Example5: Valid restriction.
Example6: known issue, fixed in future release.
Example7: MSXML fails this since it is an invalid restriction.
Example8: Valid restriction.

Thanks,
Zafar Abbas

Hi Henry,

I have double checked and done some more tests with our schemas (with
some curious results)

Regards
Andrew

>From Henry

I'll try to get some MSoft people to look at this (but first, could you
please confirm that MSXML rejects _all_ your examples) -- as Kasimir
said, your first example is equivalent to a restriction of anyType, and
that should work for sure.

I have double checked this example :

Fails with MSXML Vers 4 SP2
Fails with MSXML Vers 4 SP1
Fails with XMLSpy Vers 5 Rel 3
Passes with XMLSpy Vers 5 Rel 2

This schema fails with XMLSpy Rel 5 Vers 3 (illegal restriction of
content model for EventPayload)

However it passes with MSXML Vers 4 SP2, MSXML Vers 4 SP1, XMLSpy Vers 5
Rel 2.
