+Internal API methods
+--------------------
+
+The API here is used to manage streams and authorize. The default handlers
+work with the config parameters.
+
+.. glossary::
+
+    authorized_sid (0047 version)
+        - **jid**: :class:`~.JID` receiving the stream initiation.
+        - **node**:  stream id
+        - **ifrom**: who the stream is from.
+        - **args**: :class:`~.Iq` of the stream request.
+        - **returns**: ``True`` if the stream should be accepted,
+          ``False`` otherwise.
+
+        Check if the stream should be accepted. Uses
+        the information setup by :term:`preauthorize_sid (0047 version)`
+        by default.
+
+    authorized (0047 version)
+        - **jid**: :class:`~.JID` receiving the stream initiation.

+
+        A fallback handler (run after :term:`authorized_sid (0047 version)`)
