Bob,


Our "allornone" attribute is boolean, where True implies that all
aspects of the printing (including attribute parsing, etc) must
succeed (or be valid), else the job is cancelled.


I really like the resolution of "best-effort" in the telecon on
March 21, whereby that attribute becomes a single, job-wide attribute.

Am I correct that your "allornone" attribute is the same idea as the 
best-effort job attribute we discussed today.  The best-effort attribute
has at least two values. One is "honor-all-attributes-or-print-nothing",
and another is "print-and-try-your-best-to-honor-all-attributes".
