That seems like it will cause confusion considering _xmpp-client is used
in the XMPP world to refer to where the end-users connect their user
agents to, so basically equivalent to _submission in email.  And then
there's _xmpp-server for communication between servers.

FWIW, I would suggest _smtp-out as a less confusing label.

The word "client" is a bit ambiguous whether it refers to a user agent
or a server in the process of connecting to another server. It would
help to be more explicit about which one of these are being referred to,
or if it applies to both.

Client-DANE in the later context, enabling mutual authentication between
SMTP servers could be a nice improvement / complement to SPF & co.
