I agree: in principle, recursive functions + typeswitch can emulate
the template mechanism that exists in XSLT, but in practice it is not
as convenient, not modular and --unless the typeswitch is smartly
optimized-- probably not as efficient .

I believe it would be a great idea to introduce templates in XQuery, but
I don't even dream that the WG would envisage it before ...  let's say 
XQuery 3, in 2034...?  ;-)
