                           A code distinguishing whether an Act is conceived of as a factual statement or in
                              some other manner as a command, possibility, goal, etc.
                           
                           
                           
                              Constraints: An Act-instance must have one and only one moodCode value.
                           
                           
                           The moodCode of a single Act-instance never changes. Mood is not state.
                           
                           To describe the progression of a business activity from defined to planned to executed,
                              etc. one must instantiate different Act-instances in the different moods and link
                              them using ActRelationship of general type "sequel". (See ActRelationship.type.)
