Seemingly not.  However, 2396 supplies a generic syntax for URIs
and URI references.  The actual syntax for URIs is the union of the
known schemes and their specific syntaxes, which are defined in
RFC 1738 (which is *not* superseded by 2396 with respect to the
syntax of specific schemes) and other RFCs.
