In the most commonly used current method, the new version of the document becomes effective on date X, but contains explicit text within the requirements specifying the details of the transition and a future effective date Y. While this is significantly clearer that previous methods, where the effective dates were in the ballots but not the requirements themselves, getting it right is challenging, especially for complicated ballots.<o:p></o:p></p><p class=MsoNormal><o:p> </o:p></p><p class=MsoNormal>The intent we are trying to express, however, is simple. Before date Y, use the old profiles. After date Y, use the new profiles. As I’ve stated on previous calls, I don’t think it is particularly useful to spend time or effort on creating a document that specifies both profiles, just for the transition period, and I don’t think it’s necessary to “freeze” the profiles in order to do so. We simply need to state clearly in the requirements exactly what the requirements are.<o:p></o:p></p><p class=MsoNormal><o:p> </o:p></p><p class=MsoNormal>So I propose we do exactly that.
