+Note that the behavior of both existential and universal variables is not entirely in keeping with the [Team Submission][], and neither work quite like SPARQL variables. When used in the antecedent part of an implication, universal variables should behave much like SPARQL variables. This area is subject to a fair amount of change.

 ## Implementation Notes
 The parser is driven through a rules table contained in lib/rdf/n3/reader/meta.rb. This includes
 branch rules to indicate productions to be taken based on a current production. Terminals are denoted
