RE: [xml-dev] Are people really using Identity constraints specified in XML schema?
Come to think of it a process would not help either in the example you mention - would it? For example if the ultimate authority for hiring in Egypt is the MD and the MD hires a person who is 14 yrs - thus totally circumventing the process what do you do?
Do you reject the hire because the process does not allow it?
processes, constraints, etc, do not reflect reality - they never were intended for that purpose.
So yes - perhaps a process is more amenable to the constraint expressed here - but ultimately all of them are trying to achieve the same end goal - prevent organizational policies from being broken; as I mentioned in my earlier post - how you enforce them is a question of tradeoffs.
