I suggest to reject this errata. The name of the BGP Path Attribute is
singular, namely "LARGE_COMMUNITY" (see IANA's "Border Gateway Protocol
(BGP) Parameters" registry for "BGP Path Attributes")

There somewhat is a lack of semantic precision on when to use
"community" and when to use "communities", but there is no other
commonly accepted jargon for what we're talking about in IETF creole
language. In this sense RFC 8092 was aligned with RFC 1997. Sorry for
the confusion, but we didn't see a way around it.

If you are an implementer, feel free to reach out to me off list, I'd be
happy to help clarify, confirm your understanding of the specification
and perhaps help with interop testing.

Kind regards,

Job
