RE: [xacml] IBM Develops New Language for Writing Privacy Policies

[Tim Moses <tim.moses@entrust.com>]

Anthony - Sounds to me like the Zurich researchers recognized the value of
re-using some well-thought-out work that has been thoroughly reviewed,
rather than starting from scratch.  All the best.  Tim.

My point is that EPAL currently re-uses the partial syntax  and the syntax
is uses is that of the condition part of XACML as the condition
specification language, it does not depend on a XACML runtime, just wanted
to make sure folks did not assume that, this I would not say EPAL uses
XACML.
