Much obliged. As a case of interopability, maybe something like: entities MUST NOT send byte order marks, however, they MUST tolerate them.
I am sure there are one or two (possible no longer maintained) libraries out there that ignorantly write them out. 2 years ago agsxmpp did (qualified with a quick paroosal, so don't quote me on that) so I wouldn't be surprised at all if some others did. A little OT, is there any list of specific ammendments to 3920, I am pretty familiar with 3920 so I might miss some of the changes/clarifications. Sorry for not conforming to the list standards, I am on my phone. -----Original Message----- From: Waqas Hussain <[EMAIL PROTECTED]> Sent: 06 November 2008 09:07 PM To: Jabber/XMPP software development list <jdev@jabber.org> Subject: Re: [jdev] BOM On Thu, Nov 6, 2008 at 4:00 PM, Jonathan Dickinson <[EMAIL PROTECTED]> wrote: > Hi All, > > > > What's the official stance on BOM (Byte order marks)?

I don't think the use of the byte order marks in an XMPP stream was ever intended by the protocol designers. This looks like an oversight and should be explicitly specified in the XMPP RFC. -- Waqas Hussain _______________________________________________ JDev mailing list FAQ: http://www.jabber.org/discussion-lists/jdev-faq Forum: http://www.jabberforum.org/forumdisplay.php?f=20 Info: http://mail.jabber.org/mailman/listinfo/jdev Unsubscribe: [EMAIL PROTECTED] _______________________________________________ _______________________________________________ JDev mailing list FAQ: http://www.jabber.org/discussion-lists/jdev-faq Forum: http://www.jabberforum.org/forumdisplay.php?f=20 Info: http://mail.jabber.org/mailman/listinfo/jdev Unsubscribe: [EMAIL PROTECTED] _______________________________________________
