Media type may be sufficient to infer that the document is MathML, but it won't be sufficient to validate against a particular DTD such as MathML 2.0 DTD. It's the same situation as XHTML - in the absence of a DOCTYPE, you cannot determine whether an XHTML document is written in XHTML 1.0 (Strict or Transitional or Frameset) or XHTML Basic or XHTML 1.1 or whatever, for better or worse.
