Window Manager and multiple application windows

[Bipin George Mathew]

I actually did read about the the WM_HINTS window group in the ICCCM. To be
more specific with my question, it is not compulsory for a client who
creates multiple top-level windows to specify the window group hint - In
that case I guess there is no way for the window manager to find out the
top-level windows that "belong" to an application. Am I right?
