While I agree with that the low level module should not depend on the high 
level module (that being the primary reason I raised the issue in the 
beginning), I do not see a big issue if the top modules only provide some 
information formatted in a standard way for display purposes.

I do not think it has any issue understanding it, since it doesn't have to 
know anything about the upper module and its context. It only receives a 
name and an associated value which is a MI node list tree, which it 
understands very well as long as it only has to display it under the 
given name.

Anyway, the issue as I see it is wether to query for and display all the 
dialog related information together in single request, or by querying for 
each piece separately from a different module with a different command.
I would personally prefer to have all dialog related info (including the 
one from the upper modules) displayed in a single place with a single 
command, rather than having to make N queries in N modules.
