Openfire

Openfire don't specify any namespace of an IQ, Message or Presence stanza explicitly. This means for BOSH that all normal stanzas are within the 'http://jabber.org/protocol/httpbind' namespace. From XEP: XMPP Over BOSH:

If the BOSH <body/> wrapper is not empty, then it SHOULD contain ... One or more complete <message/>, <presence/>, and/or <iq/> elements qualified by the 'jabber:client' namespace.

but also

Note: Many existing XMPP-specific implementations of BOSH clients and connection managers do not specify the namespace of <message/>, <presence/>, or <iq/> elements, since that allows them to forward stanzas without modification (the XMPP <stream:stream/> wrapper element used with TCP typically sets the default namespace to 'jabber:client'). They instead simply assume that the full content of the 'jabber:client' namespace is a subset of the 'http://jabber.org/protocol/httpbind' namespace.

So I think maybe we should state the 'jabber:client' namespace explicitly but the clients should also work without it.

Committed a patch to revision 11617.

I've reverted my former patch.

you have to rewrite the complete xml tree like most servers do on s2s and component links.
Or use string functions to build the body instead of a xml dom, this is easier in most cases and performs better.

Committed a patch (revision 11636 and 11637) which uses string manipulation in order to perform the namespace rewriting.

Guus, please review this patch.
