There is a difference between requiring XML schema and depending on XML
schema. XQuery

 - uses the XML Schema type system
 - requires the user to use XML schema if they want typechecking for complex
types w.r.t updates. (Yes, I konw this is in the future)

This seems to imply a dependence on XML schema from where I sit.

Of course, now that I think about database vendors that implement XQuery don't
have to use XML schemas. All they have to do is push update validation to the
underlying repository and then they can use whatever schema langauge they
want.

Just to clarify:

Nowhere does XQuery require XML Schema. It will be able to query data
without schema without much problems. It will however support XML
Schemata for typing if the user wishes.

This is far from making the user dependent on XML Schema.
