With your example range (4) below (affects scan and fax,
but not print) you have neatly shown why I think that the
ranges are no help. When you add a document transform
function, an email function, an instant messaging function,
etc., these combination ranges become impractical.
We are overloading right-most subunit index to specify
function (loosely 'imaging device').
But the ambiguity goes away when there's an XML Schema
or a MIB or whatever that _does_ expose associations of
device and service with subordinate subunits - because the
one-to-many from subunit "up" is explicit. That's what
the current WIMS/SM Service and Device objects and my
several drafts of an Imaging System MIB do.
I suggest we replace this appendix with a "Rationale for
Design Alternatives" appendix (as in IPP PSX spec) and
explain why ranges of subunit indices is impractical
and not extensible.

Thanks for posting the changes so quickly.
I am still a little concerned that the case of a subunit used by multiple
functions is not clear. We discussed the subunits that use the print
function and the fax function as being in the print function index range,
but what about the example of a cover open which means the scan function is
out and the (outbound) fax function is out, but the print function is
unaffected? What range would an implementation use in this case?
Maybe we need 4 ranges:
1: affects print function alone or in combination with other functions (does
not break current implementations)
2: affects scan function exclusively
3: affects fax function exclusively
4: affects scan and fax function
