Thanks for doing this! You can add XSV, no problems, not surprisingly :-).

Can't find the reference, it didn't go to the public comments list
(email@example.com) as far as I can tell.

That's just bogus, it's required to be present by the REC.

As far as I can see the only basis for such an error message is in a
non-normative comment about derivations based on the simple ur-type.
I'll request a clarification from the WG, but as it stands I think
e.g. SQC is right and MSXML and Xerces are wrong on this one.
