Well, it doesn't really. As long as the menu file references the
correct version of the DTD, it will remain valid even if we add
extensions to later version. This is suggested down the page a little
All menu files MUST include the document type declaration, so that
implementations can adapt to different versions of this specification
The problem for us is that we don't actually validate against the
actual DTD specified in the menu file, but our own notion of the DTD,
which is clearly broken.
All fairly academic if the DTD isn't on the website, though :-)

So, I suggest
Menu files must be well-formed XML files and end in the extension
".menu". They should also conform to the menu file DTD which implies
that implementation-specific extensions to the file format are not
allowed. Implementations may stop processing if they encounter a menu
file which does not comply with the associated DTD.
i.e. if an implementation validates against the DTD specified in the
menu file, then they're within their rights to barf if the file doesn't

Yep, maybe make the version number an entity at the top of the file so
it only needs to be changed once in future.
