Re: XQuery Support (Was Re: [regrep] Implementing CCTS in Registry -further thoughts)

Hi guys,

I think xQuery will be a great idea. It's much more powerful than your query
mechanism (personal opinion!) and much more robust.
On the other hand, xPath is too weak to produce a complex query. I don't
think xPath is worth the effort.

Cheers,
Max
