Thanks for the pointer. I'm not planning to complicate more the XEP than it is now, so it should not go broader. Future XEPs may extend this, but in case where it's too complicated, implementation has always the choice to not implement it, or to have different features with different backends. ++ Goffi _______________________________________________ Standards mailing list Info: https://mail.jabber.org/mailman/listinfo/standards Unsubscribe: [email protected] _______________________________________________
