Ugh, depending on the content-type for things like versioning would
suck, people have a hard time getting that right even for HTML vs.
GIF, so trying to use it for things as subtle as versions is bound to
be too unreliable.

But maybe just using a signature to detect that it's a manifest file
of some version is enough, then manifest specific code can be used to
choose which parser version to use.
