Put a couple of comments on the wiki, but I think it is a thing that
should be discussed on the list.
In ADL 1.5 a flag 'pass_through' was added. Its definition is 'Allows
nodes required for structuring data but otherwise redundant for screen
display and reporting to be detected by rendering software'. So now we
have a GUI directive on the ADL. Shouldn't this be a part of the
reference model information (if it is never supposed to be displayed)
or part of a 'visualization template' (another different level).
I would say that more information about visualization will be needed,
and having visualization information separated between two different
places feels like a bad design move.
