The idea is that you can use Compendium in as flexible a way as needed in a meeting, but that at the end you select the key nodes for action (Questions and Decisions = I-X Issues and Activities), plus any others that will become I-X Annotations. Compendium will then parse the treee to extract the hierarchical structure to send to I-X. Constraints can be expressed as Argument nodes with supports or challenges relations to different options, one of which is marked as a Decision (= Activity). Does it make sense to map sub Issues and sub Activities as shown?
