Detailed Description

A PostCondition does restrict the progression of a user through the learning sequence.

Thus, instead of saying "You may only _visit_ this object if you did this", a PostCondition says "you may only _leave_ this object if you did this".

LSPostConditions are being applied by the LearningSequenceConditionController.
