Although it appears that reasoning in RDFS is embarrassingly parallel, this
is not the case. Because all vocabulary is treated the same way in RDF,
it is possible to extend the RDFS ontology vocabulary.
The ability permits the creation of useful constructs that are not amenable
to parallelism, and that in the end require serial processing.
