[Kent Watsen <[e-mail]>]

Let me clarify, I’m trying to close the "default 0” statement on the "local-port” leafs issue.  Whether rfc8407bis is updated is a secondary concern.  

Andy (and others), do you believe this (to never set “default” or “mandatory”) to be a best-practice for reusable groupings?  Or more specifically and better for me, do you think the  "default 0” statement on the "local-port” leafs is okay or should be removed (in the tcl-client-server draft)?
