Some addiitonal comments follow .......




The problems are only with the "job template" attribtes.


I think that we can just describe the semantics of each xxx Job attribute
and not the xxx, xxx-supported, and xxx-available Printer attribute,
just list the allowed forms (as in Jay's proposal).


Then up front we have a single discussion about the semantics of the xxx,
xxx-supported, and xxx-available Printer attributes.

One possibility that may make things more understandable, is to NOT
have the same name for the Job and Printer attribute.  For the Printer
attribute algorithmically add: "-default".
