OK, then I'll second that suggestion.

It doesn't need to be explicitly supported.  If the validator just
takes it as XML and accepts a FPI, that's enough.

But your valid.xml does have a preamble, and that is sufficient for
the validators to identify it as MathML 2.0.

Please don't let your WG specify rules about preambles that would be
in conflict with generic XML rules.  We (tool developers) will
heartily curse those who give us conflicting requirements to interpret.

We can say the .xml is
  (a) valid XML, and
  (b) MathML 2.0
That's from the FPI.  Adding the MathML icon would be straightforward.

We can say the .mml is well-formed XML, but
  (1) To describe it as mathml, we'd want at least a registered MIME type
  (2) To describe it as valid, we want a FPI.  Without it we have a
      conflict with existing practice and implementations.
