Hi,

In *Section 6* "Transport Properties" there is a point mentioning Pooling
Support. In case of unreliable datagrams, how will demultiplexing be done
on the receiver end? Streams, on the other hand, have a unique stream ID. I
found a draft (draft-schinazi-quic-h3-datagram-03
<https://tools.ietf.org/html/draft-schinazi-quic-h3-datagram-03>) that
accomplishes this on HTTP/3 but since WebTransport will have its own
dedicated connection as mentioned in *Section 1.1 *"Background" how will
this be taken forward?

Thanks,
Virat
