My small objection is just that the errata did not add the full PCReq
message paragraph in the errata (it contains another editorial issue),
as the missing part can add to read the below (similar to RFC5440);
++++++++++++++
The format of a PCReq message is as follows:
<PCReq Message>::= <Common Header>
[<svec-list>]
<request-list>
where:
<svec-list>::=<SVEC>[<svec-list>]
<request-list>::=<request>[<request-list>]
++++++++++++++
The RFC5520 had mentioned the above as differently from RFC5440 as;
+++++++++++++++++
The format of a PCReq message is as follows:
<PCReq Message>::= <Common Header>
[<SVEC-list>]
<request-list>
where:
<svec-list>::=<SVEC>[<svec-list>]
<request-list>::=<request>[<request-list>]
++++++++++++++++++
I think there may be difference between <SVEC-list> and <svec-list>
However, I don't object if the authors ignored that,
