On second thought, I don't think that will work. Part of the reason for splitting these up into separate WebIDL dictionaries is to support a hasFeature() detection method similar to DOMImplementation.hasFeature(). 

Just to make sure you're seeing the entire WebIDL blocks, you should be viewing the editor's drafts in a JavaScript enabled browser.

So for this existing WebIDL dictionary…

dictionary ScreenReaderSettings {
    boolean?   screenReaderActive = null;
    DOMString? screenReaderName = null;
    DOMString? screenReaderVersion = null;
};

…an author could do something like this: (Specific syntax TBD)

if (window.settings.hasFeature('ScreenReaderSettings')) {
	var isScreenReaderActive = window.settings.valueForKey('screenReaderActive');
}

I think we'd want to set up a different *feature* altogether for 'MagnifierSettings' to standardize properties like zoom level, zoom window size, center point, etc.
