But there will be a Terminology Workshop in the Trust Spanning Protocol TF on May 3 (see below).
• Good feedback on TAS requirements is coming from the Trust Spanning Protocol TF. That process is also likely to continue into June.
• Work continues on developing a third-generation conceptual ToIP stack diagram.
