Sure. I don't think that anything I wrote suggested otherwise? When I
was talking about "layers" of validation, I was referring to people
doing validation using different methods to address different aspects
of the validation. For example, using XML Schema to validate the
general structure of a document, then using Schematron to validate
co-occurrence constraints, and then using specialised Java code to
validate additional "business rules". There's a big discussion about
this going on over on XML-Dev at the moment...
