When HL7 implemented the board decision at the beginning of the week to make selected IP free, many of you noted that DSTUs were still marked as being available to members only. The board intention somehow was not implemented as some (including me) thought it had been clearly specified. I'm told that will be corrected shortly now that the board has clarified its intentions.
I certainly never expected DSTUs (including CCDA) to be treated any different from anything else.
It just goes to show you that what seems to be obvious isn't always.
I don't think even RFC 6919 would have helped here.
