      <t>O protocolo SCOMMP é um protocolo desenvolvido para redes

      <t>O protocolo SCOMMP pode ser implementado sobre qualquer rede sem
      roteamento, especialmente sobre redes RF half-duplex.
      Na maior parte dos casos, módulos RF já implementam algum protocolo
      parecido, mas é interessante utilziar o SCOMMP mesmo nestes casos,
      já que isso irá permitir uma comunicação menos dependente da camada
      física.</t>

v00 2006-03-15  EBD   Initial version

v01 2006-04-03  EBD   Moved PI location back to position 1 -
                      v3.1 of XMLmind is better with them at this location.
v02 2007-03-07  AH    removed extraneous nested_list attribute,
                      other minor corrections
v03 2007-03-09  EBD   Added comments on null IANA sections and fixed heading capitalization.
                      Modified comments around figure to reflect non-implementation of
                      figure indent control.  Put in reference using anchor="DOMINATION".
                      Fixed up the date specification comments to reflect current truth.
v04 2007-03-09 AH     Major changes: shortened discussion of PIs,
                      added discussion of rfc include.
v05 2007-03-10 EBD    Added preamble to C program example to tell about ABNF and alternative 
                      images. Removed meta-characters from comments (causes problems).  -->
