This service implements :xep:`131` feature advertisment.
It registers the ``http://jabber.org/protocol/shim`` node with the
:class:`.DiscoServer`. It publishes the supported headers on that node as
specified in the XEP.
To announce supported headers, use the :meth:`register_header` and
:meth:`unregister_header` methods.
.. automethod:: register_header
.. automethod:: unregister_header
.. versionchanged:: 0.8
This class was formerly known as :class:`aioxmpp.shim.Service`. It
is still available under that name, but the alias will be removed in
1.0.
