The XQuery type system is based on W3C XML Schema. To claim otherwise
implies you haven't read the document. Besides the fact that it says so
explicitly[0], in section 3 entitled 'The XQuery Type System' where it
states 

"The XQuery type system is based on XML Schema. XML Schema defines a
notion of validation for XML documents." 

But even without that statement one stumbles over XML Schema all through
the formal semantics document especially in sections 2.3.*, 3.1.1, and
3.5.*
