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.
