Bert,
these are just selectors; what I mean is that in the generated result -
the actual value set - that IS-A relationships are returned as well as
concept codes. Without IS-A relationships a user can't navigate a value
set larger than a few terms in a useful way in a real system.

does the expansion preserve IS-A relationships (at least optionally)?
That's crucial for making any value set of more than about 20 terms
usable in a real system.
I think you need to do that by additional refinements, f.e.
< 19829001 |disorder of lung|: 116676008 |associated morphology| =
79654002 |edema|
or
19829001 |disorder of lung|: 116676008 |associated morphology| =
40829002 |acute edema|
or
19829001 |disorder of lung|: 116676008 |associated morphology| =
44132006 |abscess|
