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.
