Hi Jeff-

Can you please explain why the SYN_STREAM frame is necessary? It seems to me that just removing the reference set would get rid of the need for CONTINUATION frames since there would no longer be a requirement to process all headers together as one big "jumbo block", just a requirement to process frames in order.

To be short, it seems to me that getting rid of the reference set also solves 5, 6, & 7??
