A couple options come to mind.
* Create a clearer for the attribute, and call it before setting the
value. (Calling a clearer "resets" the dirty status)
* Make your attribute lazy; this should prevent any value from being
set during construction (assuming no value has been passed to new for
it), so the attribute will not be dirty.
