From another thread in NETCONF, Juergen writes:

  I do not know whether the official tree diagram formats will 
  have ways to show say a container with used groupings collapsed.
  This may actually be useful sometimes, but this is not what you
  are look for here either. I am thinking about

   +--rw container
      +-u-- <grouping>       (I'm guess 'u' for "uses")
      +--rw regular-leaf

  Clearly, this is for a different thread...

  And I wrote back "It might be helpful to have the ability to 
  output a tree diagram that has not expanded its groupings.  
  But, as you say, for another thread."


To add to this, I wrote a module recently that defined an RPC
and yang-data around the same groupings.  An ability to 1) print
the groupings and 2) only print references to the groupings,
would've collapsed the tree-diagram tremendously.  For example:

rpcs:

  foobar
    input
      +-u-- <input-grouping>
    output
      +-u-- <output-grouping>

yang-data:

  input-artifact
    +-u-- <input-grouping>

  output-artifact
    +-u-- <output-grouping>

groupings:

  input-grouping
   +-- <full tree here>

  output-grouping
   +-- full tree here>


Thoughts?
