OK, taking on board the general mood expressed in this thread, I've 
written some alternative wording for the relevant section.

See http://philarcher.org/powder/grouping/20090106.html#wild

It still credits the WAF group but the reference is now informative and 
is to the FPWD, not their latest draft.

OK??

Incidentally, it's not implemented yet in the P to P-BASE XSLT but if 
Kevin has time to fix the query contains section of it, I am reasonably 
confident that my copy, paste and edit skills will allow me to create 
the relevant angle brackets to support this.
