More that that though...

If you have a format that can use to present record data, or you can use it
to present record metadata, then if you specify that schema in the request,
how is the server to know which of the two you're asking for?  Hence my
suggestion to assign two different identifiers for the two different roles.
Does that not make sense?

And that's one of two reason. The other reason is to be able to distinguish
in explain which of the two you support, if you support one but not the
other.

I'll claim that.

I certainly wouldn't want to try to display a record which was natively in
(say) SVG in a record metadata schema... I'd want to display the metadata
about that record in that schema.
