The empty schema has this property, in so far as it's not _really_
empty, it contains the built-in type definitions, including
xs:anyType, which is what you want. Now all you need is a schema
validator which exposes an entry-point corresponding to clause 1 of
section 5.2 Assessing Schema Validity of part 1 of the W3C XML Schema
REC [1], and use that entry point specifying xs:anyType as the type
definition to use. XSV [2] exposes such an entry point, so for
example
> xsv -T {http://www.w3.org/2001/XMLSchema}anyType [anywellformedxmldoc]
will report the document element as [validity]=valid
I don't know enough about WSDL 1.1 service definitions to know whether
they allow you to name the type defn to use . . .
