Thanks Martinas

I understand those are syntactic RDF/XML sugar. But in that case one can
wonder why they are defined in the same namespace as proper "things" which
have specified semantics.
(Agreed there is no way to change that now, just trying to figure how to
explain this to beginners looking at the spec).
Seems to me the good answer in the long run is : forget about RDF/XML an
use Turtle :)
