Hi all,

What is the meaning of NEXT-ONLY-CSID?  It isn't clear to me what the difference is between 42 and 43 below?


   +=======+========+======================================+===========+

   | Value |  Hex   |          Endpoint behavior           | Reference |

   +=======+========+======================================+===========+

   | 42    | 0x002A |       End with NEXT-ONLY-CSID        | [This.ID] |

   +-------+--------+--------------------------------------+-----------+

   | 43    | 0x002B |          End with NEXT-CSID          | [This.ID] |

   +-------+--------+--------------------------------------+-----------+

(Looks like a similar question was asked before here<https://mailarchive.ietf.org/arch/msg/spring/CAhP45_cgEQ2_1cWLFBdm8llJYA/>, but I didn't see an answer.)

Thanks,
Trevor
