I suspect that the version in guile-lib (plus the patch I sent

(Realistically, I probably can't work on anything be
st breaking changes to it.)
(Historical note: htmlprag was mostly written 18 years ago, when HTML
was different in both standards and practice. Today, I'd write the
parser very differently, though I think there's a good chance that
htmlprag will still work for one's purpose, with this change
atop RnRS again, and hopefully advancing it. `htmlprag` was
the very first Scheme code I ever wrote, and was tested on many Scheme
implementations, so porting `html-parsing` back from Racket first seems
suiting, and probably very easy.)

Part of the complexity is supporting both 1.8 and 1.9/2.0. For 1.9/2.0
