/** This class is a a transferable representation for a collection of changes
* to be done on a keyring.
*
* This class should include all types of operations supported in the backend.
*
* All changes are done in a differential manner. Besides the two key
* identification attributes, all attributes may be null, which indicates no
* change to the keyring. This is also the reason why boxed values are used
* instead of primitives in the subclasses.
*
* Application of operations in the backend should be fail-fast, which means an
* error in any included operation (for example revocation of a non-existent
* subkey) will cause the operation as a whole to fail.
