+    <action xmlns="sleekxmpp:custom:actions">

     name = 'action'

+    #: The namespace of the main XML tag.
     namespace = 'sleekxmpp:custom:actions'
+
+    #: The `plugin_attrib` value is the name that can be used
+    #: with a parent stanza to access this stanza. For example
+    #: from an Iq stanza object, accessing:
+    #: 
+    #:     iq['action']
+    #: 
+    #: would reference an Action object, and will even create
+    #: an Action object and append it to the Iq stanza if
+    #: one doesn't already exist.
     plugin_attrib = 'action'
+
+    #: Stanza objects expose dictionary-like interfaces for
+    #: accessing and manipulating substanzas and other values.
+    #: The set of interfaces defined here are the names of
+    #: these dictionary-like interfaces provided by this stanza
+    #: type. For example, an Action stanza object can use:
+    #:
+    #:     action['method'] = 'foo'
+    #:     print(action['param'])
+    #:     del action['status']
+    #:

     interfaces = set(('method', 'param', 'status'))
+
+    #: By default, values in the `interfaces` set are mapped to
+    #: attribute values. This can be changed such that an interface
+    #: maps to a subelement's text value by adding interfaces to
+    #: the sub_interfaces set. For example, here all interfaces
+    #: are marked as sub_interfaces, and so the XML produced will
+    #: look like:
+    #: 
+    #:     <action xmlns="sleekxmpp:custom:actions">
+    #:       <method>foo</method>
+    #:     </action>
