"This makes it sound like there are hard and fast rules between

permits only 3 levels of priority.   I think we should either drop the
parameter, or extend it to allow an almost arbitrary number and style
of priority statuses, even if we only define 3 for now.  I'm thinking
of the Priority/X-Priority/X-MSMail-Priority mess in mail headers.
I'd suggest a string which could be used with the relational draft to
do numeric comparisons if desired."

Personally, I wonder why priorities are considered so useful and the
option is not just dropped, but that's me.

Assuming the majority likes :priority, I agree to the above and suggest
to allow arbitrary values, like :from does, because each method might
use different data formats as sender.  For SMTP, it is certainly a
mail address, for SMS a phone number or an alphanumeric sender tag.
Saying :priority must be defined as in RFCs relevant to e-mail makes
sense for SMTP, but not neccessarily for SMS.

I think the notify extension should focus on being a framework to be
filled with methods that interface different media, inside and outside
the internet.
