Oh. I thought there were two different things:

RESOLVED: Close with no change to the language (i.e., no additional  
mechanism).

Editorial: Add some advice about how to make your ontologies OWL Full  
if they are syntactically OWL DL without distorting the modeling.

It seems like you agree with this resolution but would prefer not to  
have the advice. I think the advice is harmless at worst.

I see Ian's phrasing puts the two together in his original email, but  
I didn't think it was meant to conceptually conflate them.

I imagine some text like the following:

"For the most part, when an OWL Ontology is syntactically in OWL DL,  
you get the same entailments under the OWL Full or OWL DL semantics,  
as long as the entailments themselves are syntactically in OWL DL.  
There are a few corner cases where this is not the case, for example,  
owl:Thing subClassOf oneOf{a} entails owl:Thing subClassOf  
owl:Nothing in OWL Full but not in OWL DL. One can force syntactic  
OWL Fullness on such ontologies by adding a syntactically OWL Full  
statement that is entailed by the empty ontology (thus doesn't  
otherwise change the modeling), for example, sameAs sameAs sameAs."

I'd be happy to put something like this in the primer. I need to  
explain the alignment anyway.

Cheers,
Bijan.
