If the custom method is part of the EO class, you just need to add a ERXKey and
add it to the keys for the response or request.

"show" is ok, as long as you have a "show" or "showAction" in
PhysicianController. But for naming purposes, if you want to get a list of
practices for a physician, I would call the method "listPractices".

Yes it is ok.
