Here is an example where nesting would IMHO be at least a "nice to have"
feature: When mapping the following OWL axiom

  Class( C partial restriction(p allValuesFrom(D)) )

to RDF, here demonstrated in Turtle:

  :C a owl:Class ;
     rdfs:subClassOf [ a owl:Restriction ;
         owl:onProperty :p ;
         owl:allValuesFrom :D
         ] .

The unnested case would be:

  :C a owl:Class ;
      rdfs:subClassOf _:1 .

  _:1 a owl:Restriction ;
      owl:onProperty :p ;
      owl:allValuesFrom :D .

Somewhat more verbose, and I have to introduce an otherwise redundant name
for the bNode. This is not so nice (but of course this is not a critical
thing).

Cheers,
Michael
