I am curious.  Why has the Media Fragments 1.0 PR [1] not progressed to Recommendation status?  It was published in March 2012 and the AC review ended in April according to the Status section of the document.    Is it waiting for a normative reference to catch up?

Hi Aaron,

I have asked the Media Fragment WG for clarification (and am also cc-ing this email).

As far as I remember, features were only allowed to go into the Proposed Recommendation document if they were shown to have two interoperable implementations. Since at the time that wasn't the case for track and id features, they weren't "allowed in". Thus, it is most likely that referring to the WD document for these features is still the correct path to take.

I think, if we can now show implementations for the track and id features, that would be a good time to request the MF WG to update the PR doc.
