Regarding __messageItemDefinition, its primary purpose is to reduce XML
bloat.
In the old editor, every message gets its own itemDefinition using the
format ${messageName}Type. That itemDefinition is then linked to a data type
via the structureRef property whenever the message's data mapping is changed.
In the new editor, all messages are assigned a shared messageItemDefinition
by default. When a message's data mapping is updated, the message is linked
directly to the appropriate itemDefinition instead which has the appropriate
type in it's structureRef already.
This approach is more consistent with the BPMN specification, since messages
should reference the ID of the target itemDefinition, which is expected to be
unique. In contrast, the ${messageName}Type pattern used by the old editor does
not guarantee uniqueness and can result in unnecessary duplication of
itemDefinition elements.
