> @@ -2472,6 +2476,18 @@ corresponds to a stream which is allocated to it (i.e., odd-numbered for
 the client or even-numbered for the server) but which it has not yet
 created, it MUST close the connection with error code STREAM_STATE_ERROR.
 
+The second least significant bit differentiates between unidirectional streams
+and bidirectional streams. Unidirectional streams always have this bit set to
+1 and bidirectional streams have this bit set to 0. As a result the initial
+stream ID for various stream types is listed below:
+
+| Stream ID   | Type                          |
+|:------------|:------------------------------|
+| 0x01        | Client Bidirectional          |
+| 0x02        | Server Bidirectional          |
+| 0x03        | Client Unidirectional         |
+| 0x04        | Server Unidirectional         |

Hmm, this table is wrong too.
