"""
XMPP stanzas of type 'error' should include an <error> stanza that
describes the nature of the error and how it should be handled.
Use the 'XEP-0086: Error Condition Mappings' plugin to include error
codes used in older XMPP versions.
The stream:error stanza is used to provide more information for
error that occur with the underlying XML stream itself, and not
a particular stanza.
Note: The StreamError stanza is mostly the same as the normal
Error stanza, but with different namespaces and
condition names.
Example error stanza:
<stream:error>
<not-well-formed xmlns="urn:ietf:params:xml:ns:xmpp-streams" />
<text xmlns="urn:ietf:params:xml:ns:xmpp-streams">
XML was not well-formed.
</text>
</stream:error>
Stanza Interface:
condition -- The name of the condition element.
text -- Human readable description of the error.
Attributes:
conditions -- The set of allowable error condition elements.
condition_ns -- The namespace for the condition element.
Methods:
setup -- Overrides ElementBase.setup.
get_condition -- Retrieve the name of the condition element.
set_condition -- Add a condition element.
del_condition -- Remove the condition element.
get_text -- Retrieve the contents of the <text> element.
set_text -- Set the contents of the <text> element.
del_text -- Remove the <text> element.
