That's correct, but irrelevant. The hieriarchy is communicated with one single
MPD in a way that would be impossible using one single DAT/LDR - if you put it
together correctly, of course.

I have never used LPub so I'm not familiar with groups.

I'm not sure. But if I understand the discussion and terminology correctly, LDA
gives every object an unique object name you ask for. The problem with using
MPD:s is that, for example the objects LeftHand and RightHand are both called
"983.dat" in an MPD. No unique names. Now, to solve that poblem and to make it
*much* easier for programs like LDA if there was a tag that LDA recognizes as
LeftHand, RightHand etc, so when LDA gets there, it creates its
Minifig01.LeftHand object and inlines that file*) and so on. This tag I'm
talking about is not part of the MPD spec, but would be required as part of a
definition MPD in the LDA object library.
*) Sub-file of a specific minifig definition MPD.
MPD:s seem good for defining a model's hieriarchy when building a model library
and to find a solution to the problems James presented. But when it comes to
animation scripting, we need another soultion.
