When one considers the amount of added complexity on top - considers 3x

You are right to ask.   Thanks.
I have been clear from the rechartering that 3 standards track
encapsulations is not ok.   I haven't seen the working group indicate any
ability to have consensus on picking 1 or 2 for Standards  track.  The
charter doesn't specify intended status.

I would also note that the lack of discussion and handling of technical
concerns doesn't really indicate a lot of "working" on the encapsulations.

Yes, but very few documents are acceptable for a down-ref & there are
specific reasons the sponsoring AD feels each is acceptable.   The DownRefs
list is not that large.

As for the precedence,  it goes the other way.   By default,
down-references aren't permitted and each is a special exception for the
referenced document.   This is a loosening of the rules that never
permitted them.

Yup - the perils of auto-correct on my phone & needing to get out the email
right before the plane took off.

I am trying to be clear on the consequences of the decision the WG makes.
If this were all to happen in the least desirable way possible, yes, if the
drafts aren't professed in a timely fashion & the WG is closed,  they would
need to find an AD to sponsor them.

There is little interoperability from NVO3 after 5 years.  I am quite
disappointed with the progress of NVO3 - despite the brief period of
significant work after the recharter.

Alia
