Thanks for your hard work. Here are my comments.

To make people's life easier, I have generated a diff version against
the previous version:


I make no guarantee about its accuracy though.

Some of my earlier comments still stand. Using my previous message:

The document still makes it sound like there was consensus around the

What about:

  The Working Group agreed on using the following definition for now:

along with an editors' note saying that the definition will be
revisited in lights of the requirements found.

AC0012-A is still present under the name D-AC0001.2.1. As I said in
the email referenced above, and this suggestion was received
positively by Working Group members, I would like to drop
D-AC0001.2.1 and rephrase D-AC0001.2 into:

  Ensures that the development of identified technologies identifies
  conformance so that testing software can be constructed.

This is still present, but I guess we will revisit that after

Same comment.

Same comment.

Same comment.

I was arguing for the removal of the second paragraph entirely, not
only the second sentence, but that can wait for after the publication
since I expect it to generate some discussion.

I guess that this will also require some discussion, so I'll hold it
for now.

This change wasn't made. Is that an omission or did the editors decide
against it?

This one is unchanged, even though I thought the Working Group clearly
had a problem with the current wording. Has this been postponed?

A new comment:


  I think that it can be removed, and D-AC0013 can say: "(absorbs
  D-AC0014)". I don't see the point of leaving it around.
