Question on the sender descriptor within a PATH message...

>                                          [ <ADSPEC> ]
>                                          [ <RECORD_ROUTE> ]
> and the path message looks as so:
>       <Path Message> ::=       <Common Header> [ <INTEGRITY> ]
>                                <SESSION> <RSVP_HOP>
>                                <TIME_VALUES>
>                                [ <EXPLICIT_ROUTE> ]
>                                <LABEL_REQUEST>
>                                [ <SESSION_ATTRIBUTE> ]
>                                [ <POLICY_DATA> ... ]
>                                <sender descriptor>

>       <path msg stream> ::=      <Common Header>
>                                  <SESSION>
>                                <SENDER_TSPEC>
>                                <RSVP_HOP>
>                                <TIME_VALUES>
>                                <RECORD_ROUTE>
>                                <LABEL_REQUEST>
>                               <SENDER_TEMPLATE>
