-- A ruleset is essentially a collection of axioms and rules
-- associated with a namespace.
--
-- Rulesets for RDF, RDFS and basic datatyping are predefined:
-- see RDFRuleset, RDFSRuleset and RDFDRuleset.
-- Additional rulesets may be defined for specific datatypes.
--
-- A proof context is a list of rulesets,
-- which may be cited by a proof.
