Subject: Re: XACML and OGSA SAML AuthzDecisionQuery/Response proposals. Forwarded message from David Chadwick.


Would it be possible to devote a good portion of the agenda on 21
August (probably going until 11:30am EDT), or else the entire
Focus Group meeting on 28 August to discussion of a joint SAML
2.0 Authz proposal with the authors of the OGSA proposal?

Dear Anne

I guess we have a cultural difference in the meaning of the term
meeting. In the UK it invariably means a physical face to face meeting.
The other is a telephone conference call, not a meeting :-)

So 14 th Aug would  be no good for me, as I will high in the sky
somewhere between Colorado and NY. The 21st will be OK though, as I can
be back in the office for that day, or the 28th either.
