Thanks Chris (and Richard).

I think that what we'll do is wait for these issues to be resolved, revise the draft, and ask for publication.  The feedback we've received is positive and the draft looks to be in a good shape, so it is just a matter of ensuring that we can be proud of what we send the IESG.

Cheers,
Martin

I think the document is ready to proceed when these issues are resolved.

(I suppose another way would be to remove metadata, but I think SFrame should keep the metadata concept — it’s quite cheap and can help future extensibility). Issue #154 may also require a normative change to specify decryption failure behavior.
