I feel we need a agreeable definition of work-items. It is getting confusing already. If the goal is to avoid confusion then exceptions must be avoided.

Additionally, it reiterates the need to define "What isn't a Work Item?"

This is a philosophical issue, I think. People (and presumably form libraries) have different definitions of what "dirty" means. Yours: "The field has ever been edited" Mine: "The value of the field is different from the initial value"
