Well, to be fair, RFC 2141 and RFC 3406, which predate RFC 3986, use the
term "lexically equivalent", so I can understand the confusion. However,
draft-ietf-urnbis-rfc2141bis-urn-06 (submitted 12 days ago) removes the
term "lexically" to align the URNBIS work with RFC 3986, and the next
version of draft-ietf-urnbis-rfc3406bis-urn-ns-reg will do the same.
