Re: [Editorial Errata Reported] RFC5952 (4900)

[Juergen Schoenwaelder <[e-mail]>]

Michael,

section 2 of RFC 5952 explains how the textual representation was
originally defined, section 3 explains why tighter rules are
desirable, and section 4 finally defines tight rules that lead to
predictable textual representations. It is thus not a bug that the
texts in the different sections are different and hence I think this
errata should be rejected.
