Hi Alexey,

This is a good point.

Since data-ct needs almost all of the “normative” ABNF in media-content-type-format, I think the right thing to do would be to fully develop media-content-type-format and make it a normative reference.  (Note that media-content-type-format probably needs to be run by httpbis and emailcore [?] soon and when it is nearing WGLC, and there may be surprises there.)

This course of action would probably delay data-ct a bit; we might counteract the damage by early registration.  Since data-ct only needs an “Expert Review” registration, we could decide to do this when we have processed the reviews that are now incoming.
