In the general case even using generate-id() will not provide uniqueness -- 
the same node may be produced many times, or sometimes different nodes (in
temporary trees) are assigned the same (re-used when a temporary tree has
been disposed of) id.

This is a typical use-case for a Monad.

I would be at XML Europe next week and if somebody would be interested I can
demonstrate the current Monadic Computation implementation, which is part of
