Dear colleagues,

a 09 version of the CC draft was uploaded. This versions includes corrections (ABNF, wrong example, missing timer), resulting from the 3 sustantial comments I got during WGLC. Further there are editorials (spelling corrections, wording clarifications, example clarifications).


After WGLC I got comments refelecting different reqirements for CC running on a device and not on a server in the network, which would change some SHALLs to SHOULDs, see my last mail to the list. As I said in my opinion those changes are very useful for a more comprehensive CC solution, and therefore should be considered. I have therefore provided a 10_draft_a version of the internet draft. You can check the differences at
