Hmmm... yet more feedback that the spec isn't quite clear.
I think the spec says it shouldn't be presented (see
below).

I have to disagree here. And I think the spec is quite
clear:

On the particular issue of whitespace an <LI>, the spec is not
quite as clear. My intent was that both Netscape and Mosaic are
conforming user agents (and that in general, information providers
can't rely on how whitespace like this will be handled), but
the browsers that throw out the whitespace before and after
all the words in a block structuring element are preferred.

I don't quite follow. Could you cite your evidence for this
conclusion? A conforming SGML parser will in fact report the space as
part of the content of the LI element. But HTML, as an SGML
application, is free to prescribe whatever sort of processing it dang
well pleases with that space, no?
