Older XMPP implementations used code based error messages, similar
to HTTP response codes. Since then, error condition elements have
been introduced. XEP-0086 provides a mapping between the new
condition elements and a combination of error types and the older
response codes.
Also see <http://xmpp.org/extensions/xep-0086.html>.
Example legacy error stanzas:
<error xmlns="jabber:client" code="501" type="cancel">
<feature-not-implemented
xmlns="urn:ietf:params:xml:ns:xmpp-stanzas" />
</error>
<error code="402" type="auth">
<payment-required
xmlns="urn:ietf:params:xml:ns:xmpp-stanzas" />
</error>
Attributes:
error_map -- A map of error conditions to error types and
code values.
Methods:
setup -- Overrides ElementBase.setup
set_condition -- Remap the type and code interfaces when a
condition is set.
