---snip--- I should clarify my position. I would like:
"An XMPP entity MUST NOT send out data that is not namespace-well-formed" This includes data which it generates, and data which it routes or delivers. What an entity which is routing or delivering may do is accept data which is not namespace-well-formed, sanitize it, and then route or deliver it. > Note: Because these restrictions were underspecified in an earlier > revision of this specification, it is possible that > implementations based on that revision will send data that does > not comply with the restrictions; an entity SHOULD be liberal in > accepting such data. I agree with this. What this liberal acceptance needs to involve is sanitization.
