Re: changes to document overview (done)

Similar comment to the one on QL, for RL. Current:

"OWL 2 RL enables the implementation of polynomial time reasoning
algorithms using rule-extended database technologies operating
directly on RDF triples; it is particularly suitable for applications
where relatively lightweight ontologies are used with very large
datasets, and where it is useful or necessary to operate directly on
data in the form of RDF triples."

Is it equally true that in RL there is benefit to a small tbox and
large abox? I was under the impression that they were more on equal
footing in RL.  Suggested rephrasing is:

"OWL 2 RL enables the implementation of polynomial time reasoning
algorithms using rule-extended database technologies operating
directly on RDF triples; it is particularly suitable for applications
that want to manage relatively large amounts of data represented using
OWL, and where it is useful or necessary to operate directly on that
data in the form of RDF triples."
