Top level interactions elements provide the primary question types available in the learning interactions domains.
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.
