Dear Tero,

Yes we are refering to the 2nd last line of table 2.a.

Most of us know that you are right and what you are indicting makes sense.
However vendors have already implemented or are implementing what an
standard document says (w.r.t table 2.a). At this point and understanding
that we had some consensus on only citing work that is already published as
standard we need to refer to table 2.a as it is now (in the 2012 version).

This is strange but if we adopt the changes proposed in some of this mentor
documents, how do we ensure that everybody that has implemented or is
implementing 15.4e  (2012) will  follow this amendments which are not part
of any standard yet.

What others think, does anybody have experience on such situations?

regards,
X
