Summary:
The document is almost ready for publication as standard track document
Major issues:

Minor issues:

1. In section 2 it says "A GM  receiving the KEK_ACK_REQUESTED attribute can
choose to ignore it, thus appearing as if it does not support the
KEK_ACK_REQUESTED  attribute.". Any reason for the GM to ignore the message? 2.
In section 4 and section 6 it says the the GM SHOULD send an acknowledgement
message. Is there a case when the GM should not send and if not why is this a
SHOULD and not a MUST? 3.  In section 6 "A non-receipt of an Acknowledgement is
an indication that a GM is  either unable or unwilling  to respond".  What
about if the Acknowledgement message was lost? Any reliability procedure?

Nits/editorial comments:

1. In section 6 "Also a GM may be  willing or able to respond with an
GROUPKEY-PUSH ACK " . I cannot parse this sentence in the context of the section
