I hold exactly zero expectations of a wall switch that will work with several manufacturer's controllers.
In the XBee ZB Product Manual, p35, I find the sections "Application Profiles" and "Clusters" to be encouraging. The way I read it, if a device operates, for example, in the public home automation profile, the On/Off "command" is a standard thing. "Cluster" sure is a funny word, I'm not sure what they're getting at. "On/Off" is a cluster, as is "Color Control" and "Level Control". Maybe cluster is meant to imply a container for commands, actions, etc. Probably not a word I would have chosen.
