Are there definitive answers to 2 (Well a processor will always give you one if the set is not empty). Is A/@* a representation of the attributes of A. (I say yes). Is A/@* a faithful representation of the attributes of A? If A/@* is a faithful representation of the attributes of A why does it yields answers to questions that the original representation can't answer. So what if A/@* is not a faithful representation. Should I present the answers it gives me as a universal truth. Abstracting - If I represent a circle by two points in a plane (since that's all I need to definitively construct the circle) can I now assert that anything that is true about those two points is also true about the circle or should I be more circumspect and cognitive of possible anomalies. For my two points substitute A/@* for my circle substitute <A 1st="1" second="2" third="3" fourth="4" fifth="5"/>
