But there is no reference from a DIT structure rule to the structural

If you have a schema with multiple nameForms defined, and you take your
interpretation that nameForms take effect in the absence of DIT Structure
Rules, then you get the nonsensical case of multiple nameForms
applying to a
single entry.

Even if there is a governing structural rule for an entry there can be
more than one possible name form.

Irrelevant. There can only be one DIT Structure Rule for an entry, and a DIT Structure Rule can only reference one nameForm. For any given entry, only one nameForm may be in effect.

 From X.501(1993) section 12.6.2:

   If different sets of naming attributes are required for entries of a
   structural object class, then a name form must be specified for each
   distinct set of attributes to be used for naming.

Almost the same in X.501(2012) section 13.7.2.

And you (and others) agreed on that back in 2008:

Irrelevant. This references entries of a given structuralObjectClass that exist in different parts of the DIT and thus governed by different DIT Structure Rules.

Any implementation not supporting more than one possible name form is

=> Your argument is not sufficient.


Well in that case, it'll mean that that the DIT content rules will apply only when referring to an entry which compiles with the name form; if the same entry is referred to without compliance with the name form (situation Z), the DIT structural rule will not apply. This means inconsistency in the DIT. The DIT will be all about 'perspectives'. In situation Z, an entry may not be subordinate to one entry, but in the other, it will appear as subordinate.
