No, we don't. HTML 5/4.02/4.1 does not need to include legacy and
proprietary features, a user agent can support both "new HTML" and
"Legacy/Proprietary code" without the latter being specified in the
former.

For user agents that want to implement legacy and proprietry features,
a seperate specification can be written.

This may or may not require switching of parse modes for the markup
based on some versioning information in HTML > 4.01.
