As chairs of the TLS Working Group, we request that the IESG not approve draft-ietf-tls-authz-07 as a Proposed Standard. This document was initially brought to the TLS WG, which passed on it due to lack of interest and it was subsequently advanced as an individual submission, but IESG approval was rescinded after the disclosure of IPR that affected the document. These events occurred in late 2006 and early 2007. In the nearly two years since the previous attempts at progressing the document, the authors have not coordinated with the TLS WG. The TLS WG was not consulted prior to the start of this new Last Call. Although we recognize that opinions vary about the wisdom of advancing documents as individual submissions, this does not seem like an edge case to us. First, there is a functioning, relevant, working group: TLS. While it is true that the WG did not object to advancement two years ago, that was with the impression that it would be uncontroversial, which clearly is not the situation. On the contrary, the IPR situation remains quite unclear and there are also technical issues with the document (see Eric Rescorla's separate review), as well as at least one part of the document which is obsoleted by RFC 5246. These factors provide substantial evidence that the document would benefit from the Working Group process. If the authors wish to advance the document on the standards track, the appropriate path is to submit it to the TLS WG as a work item. TLS WG has the appropriate participation and skills to evaluate the need for this work and the suitability of this document. If there is sufficient support for work in this area (including the usual RFC 3979 IPR Evaluation), then it can advance through the standards track via the WG process. If the authors don't wish to go through the WG process, we do not oppose advancement of this document as Experimental. However, we do not believe that advancing a two year old document which is clearly in scope of an active WG is an appropriate use of the individual submission process. Therefore we urge the IESG not to approve this document.
