Learning and training: interactions domain elements (DEPRECATED)
Use the learning interactions to construct a basic set of question and response
         interaction. The domain also provides an <lcInstructornote> element,
         which you can use to provide instructor-specific information in the learning topics.
      
      note
DITA 1.3 defines two new domains for describing
                  learning and training interactions: learningInteractionBase2Domain and learning2Domain.
                  These two new domains mirror the DITA 1.2 learningInteractionBase and general learning
                  domains, but the new versions provide support for multi-paragraph questions, answers,
                  and
                  feedback. The new domains are otherwise semantically identical to the original domains.
                  For
                  backwards compatibility, both interactions domains are supported in DITA 1.3. For
                  new
                  content, use the DITA 1.3 learning2Domain elements.
