I would suggest renaming the field to "msgimportance" rather than
"msgpriority". Importance is the accepted term for what I think you are
trying to indicate. This is a standard field in X.400 and imported into
Internet mail by MIXER and VPIM. The attributes of such are "low, normal,
high".
We have debated long over the differences between importance and priority.
Priority is now considered a delivery-system (SMTP-level) attribute intended
to modify queueing behavior and is not standardized in Internet mail. In
this sense, it is doubtful if a SNAP client will have access to the priority
information even if it was there. Importance is a user-presentation
attributes intended to convey the senders sense of importance of the message
to the recipient.
Urgency as a value of importance is somewhat unusual. (I think Stephen
Covey "seven habits of highly effective people" makes a clear distinction
between urgency and importance... ) To the best of my knowledge, we have
not standardized a message attribute for "urgency".
Please don't map non-standard attributes to a standard one. If you wish to
support vendor-X's X- headers, then support the provision of separate X-
attributes in SNAP. The risk of commingling the standard and non-standard
is that the receiver can't definatively know the semantics of what was
received.

Subject: [VPIM] SNAP draft
Hi all,
After a long time, I am about to submit the SNAP next draft. During the work
I had a few things that I would like to share with you and get your
comments.
As part of the specification, the messaging server sends the message
priority and message sensitivity as part of the SNAP.
The attributes are defined as follows:
3.5.2 MsgSensitivity
If the Sensitivity header is present, the string value SHOULD be
provided in this attribute.
3.5.13 MsgPriority
Priority of message. Legal values are 'Urgent', 'Low' or 'Normal'.
If X-Priority headers is present its value SHOULD be used; values
of 1 or 2 for urgent, 3 for normal, 4 or 5 for low.
If Importance header is present, its value SHOULD be used.
If both are present, source SHOULD use the Importance header.
These 2 attributes are not mapped to another RFC or draft - as I am not sure
it is standardized.
Does any one have a comment?
