I would say that both versions say no body element in the message
stanza, however the original could have been interpreted as no body
content to the message but a body in the subject would be ok. Which is
probably why it's been cleared up I expect.
That's my view on it, no <body> at all when changing subject of a muc
room.

Hi all,
I was just noticing that some phrasing in XEP-0045 changed since I
last
looked at it.
In v1.22, Section 8.1 (Modifying the Room Subject) read:
"…The subject is changed by sending a message of type "groupchat" to
the
<r...@service>, containing no body but a <subject/> that specifies the
new subject:"
Since v1.23, Section 8.1 (Modifying the Room Subject) reads:
"…The subject is changed by sending a message of type "groupchat" to
the
<r...@service>, where the <message/> MUST contain a <subject/> element
that specifies the new subject but SHOULD NOT contain any other
element
(e.g., no <body/> element or <thread/> element)."
A client I work on, BarnOwl [1], has been, perhaps incorrectly, using
the former wording to allow for a <subject/> element along with a
<body/> element to indicate a subject for the particular message,
without changing the topic of MUC. This is used to emulate a feature
that every IM since Zephyr [2] is lacking, which allows for multiple
threaded conversations to exist in a single forum [3].
I'm interested in getting feedback on this usage and perhaps getting
it
standardized.
Thanks,
