Actually I believe OpenSP is just the parser, and the validator is the
conformance checker which uses OpenSP. Thus, OpenSP is not
non-conformant according to that, but the validator is. However, I
disagree with that statement anyway. Validators should not be
non-conformant simply because they only do their job to validate a
document and nothing else. I don't see any reason why such a statement
needs to be included at all.
If OpenSP was non-conformant, then any current or future UA that is
built with OpenSP as the parser would be non-conformant also, which
should not be the case. Since HTML is, and IMHO should remain, an
application of SGML, the use of a conformant SGML parser should not make
the user agent non-conformant.

What the? I disagree with that. HTML should remain an application of
SGML, and browser's should be built to conform properly. Aside from the
unimplemented SHORTTAG features (which can be turned off in the DTD
anyway) and the mostly undefined error handling, what about HTML 5 will
be so incompatible with SGML to warrant such a decision?

Agreed, since no existing browser I know of handles it in the most
logical and, IMHO, the most correct way (ie. when a parent element is
closed, all unclosed children elements should be closed and not reopened
after); and no two browsers that I know of create completely compatible
DOMs with any other method.
