CFC: proposed errata for ActivityPub spec

Issue 523 describes a reference error in the ActivityPub spec:

https://github.com/w3c/activitypub/issues/523

Based on this report, I have created two new errata in the ActivityPub
proposed errata <https://www.w3.org/wiki/ActivityPub_errata/Proposed>:


   - *In Section 3.2 "Retrieving objects", the first sentence contains a
   grammatical error and a mismatch in subject between the two clauses of the
   sentence. The incorrect text says "The HTTP GET method may be
   dereferenced", which is nonsensical; the HTTP GET method is used to
   dereference an identifier. Also, the sentence first refers to an "object"
   but later refers to an "activity". A possible correction is to rewrite the
   sentence as follows: "The HTTP GET method may be used to dereference an
   object's id property to retrieve the object."*
   - *In Section 3.2 "Retrieving objects", the last sentence in the first
   paragraph refers to an "activity" when describing how to dereference an
   object. One possible correction is to change the last word: "The client
   MUST specify an Accept header with the application/ld+json; profile="*
   https://www.w3.org/ns/activitystreams*" media type in order to retrieve
   the object."*

   Thanks to a for the wording for the first erratum.

   This is a call for consensus. If there are no objections on the GitHub
   issue or in this thread by the end of day 14 Nov 2025 AOE, I will add these
   proposed errata to the ActivityPub errata page and apply the changes to the
   ActivityPub editor's draft document.
