As well as CC/PP the CSS working group recently published a last call draft of "Media Queries" - a specification which goes some way to providing conditional application of style sheets and similar mechanisms. http://www.w3.org/TR/css3-mediaqueries/ This allows for a bit more privacy. An even more interesting approach to some of this was work done at the University of Melbourne on Constraint-based CSS - they actually implemented it in a browser (Amaya) but it (obviously) didn't make it into the CSS standards... cheers Charles McCN On Mon, 28 Jan 2002, David Woolley wrote: > > Mozilla/4.04 (Win95; I; ; IMP-CONT IMP-AUD) The inappropriateness of further abusing user agent comments, and the existing protocol have already been covered.
