Syntactically, of course.  The question is one of policy and consistency
within the ltru group.  Decisions like "this subtag requires additional
commentary" are properly left to ietf-languages at, unless we can
make (and live by) a statement about why a particular bit of commentary
was added there.

No, the issue (#22 on the ltru tracker) is whether to revert a change
made to the 4645bis draft.  The consensus here is clearly to *not*
do so.  The question some seem to be raising here is whether to start adding
comments for these cases where we are simply following the 4646bis procedures
for Preferred-value.  I'd rather *not* go there, unless someone specifically
makes a request to do so on the ltru list.

Agreed.  Let's please move any further discussion of this back to ltru at
