RE: XQuery 1.0 - 3.12.3 and 3.12.5

The "cast as" syntax is now almost entirely redundant - the one case where
it is still needed is where the name of the type clashes with the name of a
function. I think we're still trying to solve that problem, though I'm not
sure it's very high on anyone's agenda just now.
