rdf11-concepts: abstract should summarize, not just describe

re http://www.w3.org/TR/2011/WD-rdf11-concepts-20110830/

The Abstract should be a condensed version of the document, not just a
brief description.

the 1st sentence in 3.1 seems like a good starting point:

"The underlying structure of any expression in RDF is a collection of
triples, each consisting of a subject, a predicate and an object. A
set of such triples is called an RDF graph (defined more formally in
section 6). This can be illustrated by a node and directed-arc
diagram, in which each triple is represented as a node-arc-node link
(hence the term “graph”)."
