Hi,
Just to put the focus

The relevant text in section 5.8 in the transport document is 


"Between different versions the following things are guaranteed to remain constant:

   o  the location of the header form flag,

   o  the location of the Connection ID flag in short headers,

   o  the location and size of the Connection ID field in both header forms,

   o  the location and size of the Version field in long headers,

   o  the location and size of the Packet Number field in long headers, 

   o  the type, format and semantics of the Version Negotiation packet."


This is what we need to agree on.

Roni
