Although I registered and bought my ticket to join the meeting next week, due to a family emergency I will not be able to attend.

Alrighty then:)

What do others think about Joe's counter-proposal
which is effectively; leave D-AR006.6 where it is (under
D-AC006) and change it to read:

D-AR006.6
	The security framework SHOULD support Non-repudiation between
	transacting parties

I could also see replacing "support" with "enable" since that's
the meaning of "support" that I think we mean in this context.

I could also see adding in the "of origin and receipt" as in
my previous proposal (see below).

Comments?

Cheers,

Chris
