// Description: CompoundFile IO Permission. 
//                  It is a class for permission that will be asserted/demanded internally.
//                  Only XPSViewer (or Mongoose) code will assert this permission. 
//
//              Using it allows the following:
//                  We can have very specific targeted asserts for enabling EncryptedPackageEnevelope
//                      and CompoundFile IO APIs. 
//                  This is to provide a granular permission for CompoundFile IO operations to be used
//                  by XPSViewer to enable Encrypted Documents scenarios in Partial Trust 
//                  rather than asserting broader permission such as Unmanaged Code 
//
// !!!! Warning !!!!: No code other than XPSViewer (or Mongoose) should assert this 
//                      permission without agreement from this code owners.
