> @@ -4340,8 +4340,9 @@ The STREAM_ID_BLOCKED frame contains a single field.
 
 Stream ID:
 
-: A variable-length integer indicating the highest stream ID that the sender
-  was permitted to open.
+: A variable-length integer indicating the stream ID limit at the time the
+  sender was unable to open new streams.

That sounds like an excellent observation.

I think I'd agree to changing the definition of MAX_STREAM_ID to send the number of streams rather than the stream ID. We might also want to rename the frame to MAX_STREAM_COUNT.

There are certain aspects that are not elegant in the way MAX_STREAM_ID is defined now:
* we have two maximums; one for unidirectional streams
* we exchange counts using TP but we transmit maximum in the frame

These issues will be resolved by sending the counts.
