10. 802.11 TGw Protected Management Frames
First Recirculation Sponsor Ballot for IEEE w Draft 7.0 closed on January 18, Result: %
82 comments: 6 general, 30 editorial, 46 technical.
Public action frames have become an urgent issue now, with competing requirements from various task groups, and that issue has delayed issuing a recirculation. Coordination among various task groups to resolve the issue is on-going, and hopefully a resolution will be reached within the next two weeks, thus allowing the draft to be recirculated.

16. JTC1/SC6 Ad-Hoc ISO/IEC JTC1/SC6
Completed jtc-draft-liaison-letter-response.doc which is a liaison letter responding to the liaison request from SC6 requesting to continue using the normal fast track process and also to allow IEEE 802 to become a category A liaison. The liaison response politely turned them down.
Completed jtc-draft-liaison-response-to-sc6-documents.doc from to SC6 commenting on proposals to start a group in ISO/IEC to work on WAPI
Initiating a PDSO submission of P has been delayed for about a year as certain issues with the PDSO are resolved.
Began planning for the SC6 meeting in Tokyo in June.
