Which interface in bridge? wds/wlan or both?

When I have an AP with WDS enabled to put the wds interface in the bridge.
Do I also put the wlan1 that is the ´mother´ interface of the wds interface in the bridge?

I always do, but also forgot is sometimes. (I always use manual) and to be honest don’t see any difference.
But what is the proper procedure?

I do not put the actual wlan interfaces into the bridge. I only add the client WDS interfaces, and the VLAN interface I want to bridge the clients onto.

Would it be a ´bad´ thing if the actual interface is in the bridge where it is not really needed. (Like wds, vlan etc.).
I never noticed any problems with it, but that doesn’t mean it might not create some at times?

Somebody else with some input in this?
