4. WG status update
           * MCR still need to help Martin on large pull request.
           * EBML changes... done.
                + issue #257, requested one more day to think about it. The
                changes are fine in general, but want to make sure it precise
                enough. (MB)
           * ffv1 has been submitted to IESG by AD.

5. Work on Matroska issues.
              48 open issues
              21 open pull requests
                https://github.com/cellar-wg/matroska-specification/issues

                Next time, Steve will walk us through XSLT code to validate the
                specification.
TAG:
     "format extension"   suggestion that does not have to go into the main
     spec, because it could be added as separate spec  
     https://github.com/cellar-wg/matroska-specification/issues?q=is%3Aissue+is%3Aopen+label%3A%22format+extension%22
        "format addition"     something that has to go into main specification.
         
        https://github.com/cellar-wg/matroska-specification/issues?q=is%3Aissue+is%3Aopen+label%3A%22format+addition%22

* 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.


        6. Any other business.
