Thanks David for your update.
I am very glad you made a lot of progress. Joint meeting at GGF17
sounds great.
Out of curiosity, have you got approved new WG's charter formally?
All I can find on OGSA-AuthZ project is proposed charter dated
Aug. 18, 2005 and it looks like working draft.
Thanks,
----

>> - New charter output: 2 new versions
>> - Authorization document
>> - (The attributes document is not mentioned)

>>
>> Update and aim for a final call by the end of the month
>>
>> * Security - Review of Basic Security Profile - Core
>>
>> - 1.2: This profile is not extending the WS-I Basic Profile
>> - 1.2: Generalize the statement discussing the security profiles
>> that can be combined with this profile.
>>
>> - Agreed that this profile will not expose an anonymous channel

>> - Need to expose the extensibility elements in referenced specs
>> - Need to address (at some point) how information on what features
>> are required or supported.
>>
>> * Future plans
>>
>> Discussed plans for security design team and prioritized work:
>> - 1 Work on a Security architecture
>> - 2 How to combine security functions (security context) with
>> functional interfaces.
>> - 3 MLS profile
>> - 4 Issues raised by OGSA-Data wg and collaboration
