I was reading this chapter with 3 background thoughts 1/ avoid use/mention bugs 2/ avoid closed world assumption 3/ avoid unique names assumption This is main concern when things are written in WHERE but indeed when they are written in FILTER as kind of syntactic post-processing, then I guess all is fine. Having the examples in test cases plus bunch of corner cases in test is what I would like to spend more time.. -- Jos De Roo, AGFA http://www.agfa.com/w3c/jdroo/ [1] http://www.w3.org/2000/10/swap/doc/CwmBuiltins
