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.
