So isn't the right thing to say about HTML5 that there _is_ a
normative schema, but it's not for the surface syntax, it's for that
underlying XHTML document.  Seems to me there _must_ be such a
grammar, or Hixie couldn't be figuring out what fixups to do: the
fixups are designed to produce a tree of a certain form, and it would
be useful for all of us to document that form using a schema. . .
