Or, perhaps it should use the existing terminology in
Section 5.2.2 on pages 134-135 of the 2.2 document?
This issue is one of the many problems with the proposed
changes. They are not consistent with the existing
document. It is one of the many examples of how the
changes were assembled in a hurried fashion that is not
appropriate for something that would become a lasting
portion of the standard if accepted.

The appropriate thing is for those who proposed this
ticket to withdraw it although I harbor no illusions
that such actions will occur.
