Subject: Re: [xacml] Generalization

It is my understanding (standard IANAL disclaimers) that IBM's
patent covers only a specific way of implementing Obligations:
one in which the PDP itself interprets and fulfills the
Obligations by use of plug-in modules.  This is NOT any kind of
official statement from Sun, just my personal and private
understanding.  I encourage others to read the IBM patent for
themselves if in doubt.

I don't think Tim's generalization and its typical use of
Obligations would use such an implementation, since the standard
model is that the PEP interprets and fulfills the Obligations,
and not the PDP.
