+/** 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.
+ *
+ * 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.
