Thank you John for all the useful comments, here and in the pull request. I think we may need some iteration in order to improve.
I agree that New Terminology need to be explained. In the Specific case of "critical event" we should probably avoid having it in out test spec.
In the test management approach, test cases refers to Verification Elements (REQ-ID-V0X) and not to requirements. Probably this need to be explained in the test spec somewhere.
The formatting will remain an issue, until the export script will not improve.
We can remove completely the old naming convention, since there are test cases that have already been executed. However new test cases no Draftm shall not contain the old naming since it is not usefull.
I will fix the reference problem.
There shall be no difference in the "old" content. As you confirm lather in your comment.
In terms of approval of the new content, I suppose that a RFC should be used.
