I was just thinking the same thought. You would have to escape the <
brackets to use them in HTML (the circle closes :-).

Let me try this thought. If we treated the UR* within angle text as
SGML markup, then it wouldn't break. To do that you need the pattern

<id anything*>

Which is to say you need a blank after the id. So as to limit the
amount of SGML definitions one would need to create, let's say that
there is a single SGML element used here, URI, for example. Then, the
Thing That Won't Break SGML looks like

<URI uri-spec>

Ugly. Perhaps non-orthagonal. A redefinition of something that's
already in HTML. But, it won't break SGML (unless I am missing
something).
