The following Remoting attributes are deprecated:
outbound-connection
local-outbound-connection
protocol
security-realm
username

The list is correct except the fact that outbound-connection and local-outbound-connection are resources, not attributes.

Also we should probably mention which resources the mentioned atributes pertain to (protocol, security-realm, username) - these are attributes of the remote-outbound-connection resource, not of the remoting subsystem itself.
