RFC 3986 defines the syntax for "URI" and "URI-reference", see
specifically section 4 and 4.1 of RFC 3986.  To avoid confusion, I
suggest:

     "The uri type represents a Uniform Resource Identifier
      (URI) as defined by the rule 'URI' in RFC 3986.

or "the ABNF rule 'URI'..."

(side note, is it better to refer to STD 66 rather than the RFC?)
