Does anyone here write their own customized AutoYaST scripts for building SLES servers?

I'm not talking about generating them with yast2 autoyast.

If so, have you found a way to verify the syntax? xmllint is good as far as telling you that the XML syntax is valid, but with an upto date DTD, it can't tell you anything more, and the shipped DTDs are out-of-date.

I've opened a ticket with Novell on this, but who knows when and what I'll hear back.
