Markup is just a frontend, it can work with anything. In fact, 
history only returned to where it started: UI was described in 
DSL since early versions of Windows (resources), you couldn't 
waste RAM on UI-building code, instead OS was instructed to read 
dialog resource and build the window for you, the resource was 
discarded right away, every byte was counted.
