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.)
