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.
Example error stanza:
<error type="cancel" code="404">
<item-not-found xmlns="urn:ietf:params:xml:ns:xmpp-stanzas" />
<text xmlns="urn:ietf:params:xml:ns:xmpp-stanzas">

Stanza Interface:
code -- The error code used in older XMPP versions.
condition -- The name of the condition element.
text -- Human readable description of the error.
type -- Error type indicating how the error should be handled.
Attributes:
conditions -- The set of allowable error condition elements.
condition_ns -- The namespace for the condition element.
types -- A set of values indicating how the error
should be treated.
Methods:
setup -- Overrides ElementBase.setup.
getCondition -- Retrieve the name of the condition element.
setCondition -- Add a condition element.
delCondition -- Remove the condition element.
getText -- Retrieve the contents of the <text> element.
setText -- Set the contents of the <text> element.
