And ACTUATE="AUTO" says that it is, in This is what I am waiting for guidance on :-). Some people such as Eliot (and I as a humble follower), see 'resource' as a point. Others appear to use 'resource' to represent a finite piece of information. If the latter is, in fact, the ERB's view, then the question of where to 'insert' the other information is critical. If you find my earlier analysis useful, I'd be grateful for comments as this would give me confidence to implement it (or not!).
