Aaron demonstrated some very cool techniques using XPath assertions to validate XML documents (specifically the contents of SOAP messages). He uses SOAP extensions and attributes that indicate which XPath assertions to apply to a given WebMethod. It apparently is much faster than doing full schema validation, and easier to set up, since most of the time you really only want to assert a few key requirements and don't need to validate the whole data structure exhaustively. I hadn't heard or Schematron before, but apparently is uses a similar technique using XPath assertions. There is a .NET implementation of Schematron here.
