The MIX specification is built on layered services that have defined errors. This enables the core MIX specification to reflect primarily the successful use case, as in almost all cases the error reporting of the layer service provides what is needed. A message sender MUST be prepared to handle any valid error from the layer services. When a message receiver encounters an error situation, it MUST use the most appropriate layer server error to report this issue back to the sender. For example a message receiver might use the "not authorized" IQ error in response to a MIX disco that is not authorized. Errors for the following layer services need to be handled for MIX:

A MIX channel MAY support message retraction, where the sender of a messages or an authorized administrator deletes a message. If this is done the original message MAY be replaced by a tombstone. The protocol to request retraction does this by adding to the message a &lt;retract&gt; element qualified by the 'urn:xmpp:mix:1' namespace as shown in the following example.
