Hmm, that's pretty wild but I think I've seen something like that in
xml/xslt.
What happens if you have the space before the slash? Does SGML ignore
whitespace there? I know an earlier version of NS needed the whitespace.

So, this:
<p />does this/
<p>does this</p>
That implies to me that / should join the list of entities that should
be escaped as "<" and "&" are.

Well, I realize that <br /> is not valid in html 4. From what I can tell
it is required in xhtml, which I have no desire to use since it gives me
nothing tangible over html, but what I was thinking was whether this is
going to be needed in html 5 which will get here someday. Or not.

On a side note, I notice an ever increasing number of pages with an
xhtml doctype.
