Re: %HTML.Version for strict.dtd

I started to get complaints about the validation service not
being able to recognize HTML 4.0 strict, so I hacked my copy
of the strict DTD to include the %HTML.Version attribute.

I don't like modifying published DTDs without my changes being
authorized by an official source (errata.html). In this case
the change is pretty innocent, but I would still rather not
do it without the error being acknowledged first. :/

Here's a diff -c of my changes:

Subject: %HTML.Version for strict.dtd

Hi,

I just noticed that %HTML.Version seems to be missing from strict.dtd.
Is this on purpose?

www20: /afs/w3.org/pub/WWW/TR/REC-html40> egrep -i html.version *dtd
frameset.dtd:<!ENTITY % HTML.Version "-//W3C//DTD HTML 4.0 Frameset//EN"
loose.dtd:<!ENTITY % HTML.Version "-//W3C//DTD HTML 4.0 Transitional//EN"
loose.dtd:<!ENTITY % version "version CDATA #FIXED '%HTML.Version;'">
www20: /afs/w3.org/pub/WWW/TR/REC-html40> 

I use this "version" attribute in the validation service to see
which DTD the SGML parser used on the document; since it seems
to be missing from the strict DTD, the validation service currently
says "unknown" for validation results with 4.0 strict. :-(

I haven't researched this very carefully yet, but the above grep
results seem to indicate that it isn't defined for strict.dtd?
