Hello Salvatore,

I don't know that's why I'm asking. I can't see anything special about 
the ALPN registry versus any other registry if we're using it as an example.

Do you have an answer for the second part of the previous email?
i.e One thing I'm still missing is how you specify multiple app/alpns 
(whatever we're calling them) being used in a single SCTP association, 
without using datachannel?

Regards, Christian
