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