You have two choices here, basically depending on whether you think of
 `CSS` as a state-carrying registry, or a namespace object full of 

The distinguishing code is 
`window1.CSS.registerProperty.call(window2.CSS, ...)`.

- If `CSS` is a state-carrying registry, then this should register the
 property on `window2`.
- If `CSS` is just a bag of functions, it doesn't matter what the 
`this` value you call them with is, so this should register the 
property on `window1`.

To access `window1` you'd use "this `CSS` interface object's [relevant
 (Alternately you could store the state on the `CSS` interface object 
itself, instead of grabbing a window.)

To access `window2` you'd use "the [current global 

In both cases you could add "...'s [associated 
 if you wanted things to go away during `document.open()`, which 
replaces the `Document` but keeps the `Window`.
