 ### Identifying Negotiated Version
 
 An in-network observer assuming that a set of packets belongs to a QUIC flow

-version 1, if the version number in the Initial packet from a client is the

 The negotiated version cannot be identified for flows for which a handshake is
 not observed, such as in the case of connection migration; however, it might be
