XML validation rule

[Jake]

Hello,

I'm looking for a rule language and engine that can be used to
validate XML document. I want to assert constraints on document
content that are not specified in the XML Schema. I've searched online
and it seems that XPath and XSLT or Perl can be used for this purpose.
But I'm wondering if there is any simple rule language that is
specific just for XML validation?

Thanks,
Jake
