Strawman structures for learning/training doctypes

Here's what I have from my notes on today's discussion  - leaving tag names out of it
overview - topic type, specialized from topic, containing specialized sections
summary - topic type, specialized from topic, containing specialized sections (some may be reused from overview)
assessment - topic type, specialized from topic, containing/grouping the following specialized topics:
        single-select - specialized from topic with specialized sections for the question content, answer options, and feedback
        multi-select - same as single-select but with different semantics
        open-question - specialized from topic etc.
learning map - specialized map type, with specialized metadata for duration, audience, etc. - and potentially some default structure/sequence - eg start with overview, finish with summary
Net: 6 topic types expressed in 3 document types, 1 map type expressed in 1 document type
