Re: [netmod] [Editorial Errata Reported] RFC7317 (4795)

All,

Regarding the oddity in the body of the notification message from the RFC Errata System (sent 2016-09-05), i.e., the replacement of "$0" with "RFCORIGINAL_TEXT", we will fix this error in the mail generation system.

As far as the erratum itself, we note that it is accurately displayed (and marked as "Rejected") on 
https://www.rfc-editor.org/errata_search.php?rfc=7317&eid=4795.

Thank you.
