Heh, indeed. Yes, concise and clear help is important. The goal is not
to dilute the semantics by adding new properties, but by providing properties
that better map to users' / developers' vocabulary.
Thus, I think it would already be helpful to not use numerical values
(such as priority 1 .. 10), but instead use adjectives such as 'critical',
'major', 'minor', etc.

For example, at CodeSourcery we use a variety of bug trackers, all with
a severity attribute with enumerators

critical: "This issue leaves you completely unable to make progress"
serious:  "This issue is causing substantial impact to your progress, but a workaround exists."
mild:     "This issue is merely an annoyance, not preventing progress."

priorities may exist, too, but, as I said, are merely a means to assist
developers to prioritize their work, and thus, aren't displayed to users.

Anyway, as suggested earlier, I'm holding back more schema-related
suggestions until we have a live tracker to play with, and all interested
people are subscribed to the meta-tracker.

Excellent, that gives us three types of users, all with different
access rights to the tracker. Again: the goal here is not to make things
more complex than necessary, but instead to simplify the UI by removing
items / transitions that aren't meaningful or valid anyway.
