printermib - compliance statement(s)

["Wijnen, Bert (Bert)" <bwijnen@lucent.com>]

Following is a discussion on the differences between
  <draft-ietf-printmib-mib-info-13.txt>
  RFC1759
The question is if they can just use the "updated"
prtMibCompliance or if they need to deprecate the
existing one and add anotehr one.

I am kind of inclinded to let it go... 
Opinons?

To me it feels that that is the correct way to do it.
Your "the new one is less strict than 1759" makes me think...
if you and all the major implementers of this MIB agree...
then maybe it is OK. But at least add something to that effect 
to the descitption clause.

If we were strict, then the old compliance statement should
have for objects that now have one of the new (extended, e.g.
with additional enumerations) TCs, that OBJECT listed with a 
SYNTAX of the set of enumerations that just existed in 1759.

Not sure how strict we want to be for a recycle at PS.

Other opinions?
