Overview

A language (LanguageDefinition) is a collection of component definitions. It is also known as a component set.

For example, Window, Button and Combobox all belong to the same language called xul/html, which is also known as zul.

Component designers are free to designate a component definition to any component set they prefer, as long as there is no name conflict. In additions, it is OK to use components from several languages in the same ZUML page.
