This, as well as your other message, relates to the document type
definition, not to the validator that performs a check against it.

You can write a DTD you like and check against it. Beware however that the
W3C validator is not well-equipped to handle it: it is oriented towards
checking against W3C-approved DTDs. The WDG validator is more useful if
you check against a "custom DTD".

Regarding custom DTDs, you might wish to check
http://www.cs.tut.fi/~jkorpela/html/own-dtd.html
where I also describe a "tagsoup DTD" that you might use as a basis.

That will just increase the odds of causing damage. But validators are
blind to such issues. If you wish to use such tags and validate, then
select or write a DTD that allows them. Validators care absolutely nothing
about what works on a browser or another.

I'm sure you are on a completely wrong track, but it _is_ possible to make
some use of validation even in that case. For some values of "use".
