After some puzzling on this for some time, I'm wondering exactly what the purpose is of the "blocks" value. If this is what is desired:

Sequential project
	next action 1 in a block context
	action 2 blocked
	action 3 blocked

Isn't this already the equivalent:

Sequential project						
	action 2 blocked by any incomplete subaction
		next action 1 in a skip context (such as waiting for)
	action 3 also blocked

Granted, in the second example, action 2 is an action group. But the goal of blocking is nonetheless possible to achieve with a skip context. Or is my thinking messed up somehow?

Edit:
Whoops! Waiting for is a block context. I guess what we don't have now is a skip context. Which would be basically a non-action, a note that is not attached to any action.

Edit 2:
Whoops again. Waiting for is a skip context, as I thought (it's not set to allow next actions.) So it will block action 2, but not action 3. Sorry about the fogginess -- shouldn't try to think after a long day of research.
