Subject: RE: [xacml-dev] new view for access control

I am not sure why one wants to extend XACML for this purpose.  It should be fairly straightforward to develop XACML bindings:  all what is needed is to define the context of such an operation.   If you describe the information flow operation in a form of some canonical values, you may use XACML to define access policy for it.

Subject: [xacml-dev] new view for access control 

  Access Control can be generalized to take into account dissemination of information
 this is natural because actually access control systems allow local control of information, however in over systems the information must be followed after its dissemination to grant end to end security. 
  Thus, specification language for information flow control may be obtained by extending available languages for Access Control (i.e. XACML) to incorporate clauses describing rules granting the legality of information flows.
