"Good" and "bad" here apply to document instances.  "Good" means
compliant xhtml+(mathml|svg)*; "bad", as I casually used it, means
other.  My only point is that a user agent should parse as xml a
document whose preamble indicates xhtml even when the mimetype is
text/html.  Or, if that is too hard or too politically difficult,
going forward the WG should provide a formula for the front of a
document that asks for an xhtml parse.
