Prefix Resolver.

This package is an internal resolver for extracting all elements with a specified prefix from RDF. In particular, this is useful for sequence elements from RDF. These elements are referred to with predicates of the form rdf:_n, where n is the number of the element in the sequence.

This resolver searches the string pool for all nodes starting with a prefix, and returns the results. The remainders of rdf:_ strings are guaranteed to be numbers, simply because there are no other options defined in the rdf namespace.
