There's a bit of ambiguity with this
"which has a single structural object class as the most subordinate object class"
What do you mean by 'most subordinate'? Is it that there must be no parallel entries at the same level in the hierarchy?
It's always better to provide a reference to the full text of a quoted text.
The hierarchy in this case is the the structural object classes hierarchy, not the directory information tree (DIT). Read in RFC 4512 about what SUP in object class description means:
http://tools.ietf.org/html/rfc4512#section-4.1.1
Note that there's also an attribute type hierarchy defined with SUP.
Yes, I know that.
Actually the question was --

Yes.
Ciao, Michael.
Ok, but I've another question related to this.
Suppose this is the superclass chain --
A -> B -> C -> D -> E -> F -> G
Then for D, the superclass chain is A -> B -> C, and in this chain D is the most subordinate. For F, the superclass chain is A -> B -> C -> D -> E and here too F is the most subordinate.
So what do you mean by the 'superclass chain'? The whole chain A to G or is it relative to a particular object class (because each object class at a different level will have a different superclass chain).
