I thought about this, but the TITLE isn't unique.  It's not 
like a filename, since the URL serves that purpose.

One view is that the parser (if it's dtd driven) is the DTD+parser code, so in
order to make the parser more lenient, you can choose which one you
want to modify. I know people cringe when there's talk about hacking
the DTD :)  There's the argument that if you modify the DTD, you'll
have to modify every DTD that comes out next -- but the same goes for
modifying the parser.   If I modify the parser to be more lenient, then
I have to modify the parser again (potentially) when a new DTD comes out
in order to be more lenient w/ that DTD.

I'll probably have to modify the parser anyway, becuase there's some
things I can't handle by only modifying that DTD.  So there's a good
argument for 'if you're going to modify someone, keep all of the 
modifications in one place - the parser code (and leave the DTD alone)'

I'll either end up creating a 'lenient DTD' and/or a 'lenient parser'
- I'll go off and think about it and see how hard it is to modify the
parser itself.  I guess this is the problem of having the HTML 'browsers' come
out before the HTML 'generators' :(
