This is a little unfair to the OpenID 2.0 specification, since in
order for a document to BE valid HTML[1] or XHTML[2], META tags are
only allowed to be in the HEAD.

It might have been nice for implementers if that relevant bit of
information were duplicated in the OpenID 2.0 specification, but even
without it, the requirement is well-specified.
