I'm certainly not suggesting to have all the features of XQuery in XPath NG.
I'm actually just suggesting a very few additions of means for abstraction:
functions, variables and function libraries. Incidentally this makes XPath NG
Turing complete, but I don't think that means that XPath NG would be a full
fledged programming language. It would just be a languge suitable for very
specific XML related programming tasks.

But also, modularity would let an implementor to just provide the node
selection parts if he/she so see fit.
