I've obviously been misled by the discussions on comp.mail.mime for
which my apologies: I thought there actually was a MIME.DTD around.

In that case, nor do I, and I'm not sure that mail as a concept could
easily be made the subject of a DTD. Mail messages vary so widely (and
wildly) in their content that even a single all-embracing DTD probably
couldn't cover all the things people want to do in mail messages.
What might be practicable though would be a header like X-DTD: <name>
which could be detected by MUAs and cause a switch to a display system
which would implement the specified <name>.dtd, but I'm still not
convinced we need it.
