Hi all,

Just had an email exchange with Dirk von Hugo that results in the following
change to Section 5.1.1.4 of our draft.

OLD
   With QUIC it is possible to support the ATSSS switching and steering
   functions, but splitting is not yet supported.  Indeed, QUIC supports
   a connection migration procedure that allows peers to change their
   transport coordinates (IP addresses, port numbers) without breaking
   the underlying QUIC connection.

   While no support for ATSSS splitting has yet been developed for QUIC,
   extensions to Multipath Datagram Congestion Control Protocol (MP-DCCP) 
   [RFC4340] to provide support for splitting data traffic of UDP and plain
   IP flows across multiple paths on a per-packet level can be found in 
   [I-D.ietf-tsvwg-multipath-dccp].
END

Best,
Adrian
