[xquery-talk] Schema in xquery

[David Lee]

I've been contemplating the relationship between schema and type in schema aware xquery.
Is xquery strictly tied to XSD? That is,  could an implementation support another schema format such as rng to provide for the type system?  Without conversion to XSD?   Is validation strictly bound to type assignment?  
Would it be valid XQuery to allow for some totally new type definition language as long as it produced XDM? Or is the language strictly bound to the XSD model?
It's just becoming increasingly aware to me that were mixing document validity checking too tightly with a type definition .. Where their roles may overlap but are not the same.
