Yes, of course the format exists :) What I meant is that it can't be incorporated transparently into (X)HTML, which was part of the original scheme. In my case it would have been a way of representing characters so obscure that unicode never bothered with them. Some of my browsers will recognize some kinds of xml entities, but svg images? Nuh-uh. Browser becomes resolutely deaf, dumb and blind.
