Thanks for looking at this!

The " />" style doesn't validate for html4, that's what I was going on.
It certainly doesn't make my browser explode, but I wanted that little
green checkmark! If we can live with that, that's fine, or I can try to
come up with a less hacky way of handling closing tags -- a macro maybe.

I'd be happy to leave the CDATA escapes in there, since it really
doesn't seem to make any difference, and the implementation is ugly. I
think I'm erring on the side of pedantic correctness.

The xmns declaration, on the other hand, seems quite meaningless for
anything that isn't xhtml (even if it doesn't actually break), and it's
only a couple of lines of code to deal with, I'd rather keep that in
there...

Thanks again,
Eric
