Models: DIT Content Rules and AUX object classes

[Hallvard B Furuseth <h.b.furuseth@usit.uio.no>]

[Models] 4.1.6 (DIT Content Rules) says:

  An entry may only belong to auxiliary object classes listed in the
  governing content rule.

Even if the content rule has no AUX part?  If so, is it possible to
specify that all auxiliary object classes are allowed?

Or does no AUX mean that all auxiliary object classes are allowed?
If so, I suggest it is added that e.g. "AUX 1.1" can be used to say
'no auxiliary objectclasses are allowed'.
