That's fine, as long as you realize that if you do not conform to the DTD,
what you are writing is not standard HTML.

HTML is an application of SGML.  Any valid extension of SGML can be
defined in a DTD.  If you do not use a DTD, you had better have some
other method of a) ensuring that your description is non-ambiguous,
and b) ensuring that it is valid SGML.  A DTD is simply a very
convenient way of covering these two points.

Nope.  HTML 3.2 does not define any semantics for CLASS, or ID, and only
minimal semantics for STYLE.  If what you mean is that the W3C has stated
an intention to include these features in a future version of the standard,
you are absolutely correct.  They are _not_ part of 3.2, however.
