Right. Among other problems. This is indeed a pretty old idea that has use cases, but hasn't arrived at a standard treatment. For example, it isn't clear what browsers should do *by default* with desc/title in svg (there are many useful ways of using this stuff, but different users actually want different things), something that many browsers now implement. It has been a while since I even tested what does happen... cheers Chaals -- Charles McCathieNevile Opera Software, Standards Group je parle français -- hablo español -- jeg lærer norsk http://my.opera.com/chaals Try Opera 9.5: http://snapshot.opera.com
