I wrote an external method that uses Graphite, Sping and PIL to

set up for a ZClass tolerant of the Role-centric approach followed by
ZPatterns. For example:
I have two Specialists, DocumentedProducts and Products. The Products

An Organisation can play the role of Customer and of Requester. In this
case the Requester specialist will remap from the Customer specialist. In
terms of roles all Customers do not play the role of Requester. Would it be
correct to say that the remapping to Requester only occurs at that point

How will one implement the remapping of an object from on to another
