ACTION from last time:
==> issue #257, requested one more day to think about it.

We created issue #279 to introduce some new text to better explain
what a Global Element is, and why it does not end an unlimited size
Element.

* Thank for reposting of draft-ietf-cellar-tags-02,
draft-ietf-cellar-matroska-03 and draft-ietf-cellar-codec-02

* The personal draft-weaver-cellar-flac-00 did not get reposted.
I believe that we adopted it, so it should have been reposted with a
draft-ietf-cellar-flac-00!

reposted today, thank you.

5. Any remining EBML issues.

none known.

6. ffv1-07 could be reposted in v3 format.
ACTION: mcr to ask DataTracker and RSE if they are ready for this.

7. Work on Matroska issues.

Closed issue #325 (merged).
Discussed issue #334 and related issue #308.

8. Any other business.

Matroska Pull request #318 will be on the agenda for next time.

Meeting will be moved to an hour earlier, until the time changes.
Currently it is 23:00 Berlin, so we will anchor the meeting to 22:00
Berlin time.

TAG:
"format extension" suggestion that does not have to go into the main
spec, because it could be added as separate spec

"format addition" something that has to go into main specification.

* As the WebM will not be defined, remove all of the WebM specific
stuff.
* MCR suggests removing it from the Matroska document, and leave the
history for others.
* MB: DivX is also not part of Matroska. Also concerned about how the
Matroska project presents the WebM/DiVX vs core Matroska elements. The
spec will be huge, so take things out.

* define how to add unpredictable data to the Matroska, so we could
track things that are added. Not just WebM, but also a libmotrsaka as
well.
* extension data would be on their own lines, and revision history
would be clearly.
