"xyz" as shorthand for [ rdfs:label "xyz"]

I came to realize that
  :s :p "xyz".
could be seen as a shorthand for
  :s :p [ rdfs:label "xyz"] .
(for p different from rdfs:label)
So that object is actually some thing
which carries a rdfs:label.
The shorthand is convenient when
no additional description of that
thing is needed, but when additional
descriptions are needed one cannot
use the shorthand but instead e.g.
  :s :p [ rdfs:label "xyz"; rdf:type :C ].
Such things can then also be in
subject position of course.
