This long term is a frustratingly long time coming.

Indeed.  It was IMO a valid stopgap choice for a time.  But how long
does that extend?

Exactly my view (surprise:-).  But Page Valet also has some pretty good
heuristics, which apply when the user leaves it set to auto.  There's
no reason W3C shouldn't adopt the same.  Basically you select on
content-type, and just explicitly sniff for the XHTML1.0/AppendixC
doctypes as a special case in text/html.  But we do that already!

Schneegans is offering a different service to any of the DTD-based
services.  As with the Relaxed service, we should welcome it as a
useful tool that _complements_ DTD validation.  But for HTML and
XHTML we still have a bottom line that they are expressed by DTD,
so this must remain the bedrock of the validator, notwithstanding
its limitations.
