There is no need for parameters for XUpdate and XPath but keep in mind
that XQuery has the notion: "declare variable $myvar external;" which is
(AFAIK) thought for parametrized queries.

Wouldn't it be best to mirror the existing XQuery & XPath Data Model? It's
basically an extension of XML Schema (it wraps all kind of types into
"xqdm:Foo" objects and provides accessors to the data load) and can be
serialized to XML easily.
