I took this to mean that the window manager would basically list all the 
atoms it knows about - this allows the toolkit to make some decisions about 
things like window type/state etc.

For instance, I added code to Qt that detects whether or not maximization is 
supported - and if it is, I use NET speak to the window manager when I want 
to maximize a window.
