Plugin stanzas marked as iterable will be included in the list of
substanzas for the parent, using ``parent['substanzas']``. If the
attribute ``plugin_multi_attrib`` was defined for the plugin, then
the substanza set can be filtered to only instances of the plugin
class. For example, given a plugin class ``Foo`` with
``plugin_multi_attrib = 'foos'`` then::
parent['foos']
would return a collection of all ``Foo`` substanzas.
