Is this correct? It is my understanding that XAML is the client language that is used in WPF and Silverlight (which is a subset of WPF). Both WPF and Silverlight can be used for desktop or web development (although WPF leans to desktop and SL leans to web).

No, you are right. There are just small API differences in terms of available components.
