XHTML 1.0

Hi guys,
It is incorrect to refer to existing browsers as "SGML-based". I even
wonder if there are any...

Section 4.1.1 reads:
Although overlapping is illegal in SGML, it was widely tolerated in
SGML-based browsers.

"SGML-based" should be replaced by "existing" or something like that.

Thanks.
