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, -Alejandro [1] http://barnowl.mit.edu/ [2] http://en.wikipedia.org/wiki/Zephyr_%28protocol%29 [3] http://stuff.mit.edu/afs/sipb/project/doc/izephyr/html/node23.html
