[P1619-1] IEEE RevCom approves P1619 and P1619.1

Thank you Shai for the clarification.  I remembered some such discussion, but forgot where it was!

I think this discussion is relevant to both P1619 and P1619.1 because both standards specify XTS, which in turn is based on XEX -- so I've copied both lists.

This matter was discussed and resolved long ago, as you can find in
the email archive, see in particular the message from Sep-28, 2006

The bottom line: Phil did not claim any IP regarding XEX, nor does he
know of anyone else who might have such a claim.

Also please note that discussions of XEX/XTS should be carried out at
the 1619 mailing list, not the 1619.1 mailing list.
