It depends what you're on about.   These xatoms are nothing more than
hints for interoperability.  Setting some of them is allowed (such as
WM_NAME) but settings others (such as WM_CLASS) is not -- and in the
case of WM_CLASS is only allowed to happen by the client when it's in
the WithDrawn state.

You can't arbitrarily make up or assign random bits of data to windows
to "tag" them in some way, that's not how it works.

Confer with xprop(1) for examples.
