8. Changes since RFC 2304 specification

   Although there are no major or technical changes from RFC 2304
   specification, this section briefly describes where updates and
   clarifications were introduced:

   -  considering the case that telephony systems do not conform any
      more to the "single/few" Public Operator paradigm, the old
      definition "PSTN - Public Switched Telephone Network" was changed
      into the more adequate "GSTN - Global Switched Telephone Network"
      one.  However, in order to remain consistent with the previous
      specification, the ABNF variables names were not changed.

   -  section 7 "IANA Considerations" and the IANA registration forms
      for the "FAX" "service-selector" and for the "T33S" "qualif-type1"
      elements were added;

   -  an explicit list of "new terms" with explanations was added to
      section 1.1;

   -  the case when multiple T.33 subaddresses are present was described
      more explicitly in order to clarify how to handle them (section
      4.1);

   -  in section 3 the language describing "mta-I-fax" was updated to
      better describe its relationship with an Internet Mail address;

   -  in section 4., the quoting rules of the "fax-address" and their
      practical use was made explicit both in the definition of "fax-
      email" and in the Implementors' note;

   -  the Author's Address was updated;

   -  the References list was updates to substitute ITU E.164 (1991)
      with ITU E.164 (1997).
