+ * Represents an operation on catalogue(s).

+ * An instance of this interface performs an operation on one or more catalogues and
+ * stores intermediate and final results of the operation.
+ *
+ * The first catalogue in its argument(s) is called the 'source catalogue' or 'source' and
+ * the following results are stored:
+ *
+ * Messages: also called 'all', are valid messages for the given domain after the operation is performed.
+ *
+ * New Messages: also called 'new' (new = all ∖ source = {x: x ∈ all ∧ x ∉ source}).
+ *
+ * Obsolete Messages: also called 'obsolete' (obsolete = source ∖ all = {x: x ∈ source ∧ x ∉ all}).
+ *
+ * Result: also called 'result', is the resulting catalogue for the given domain that holds the same messages as 'all'.
