Language Definition

A language definition defines a component set (aka., a language). For example, ZUL and XHTML are two component sets.

To define a language definition, you have to prepare a file called /metainfo/zk/lang.xml and makes it available to the classpath (such as in a JAR file, or in WEB-INF/classes of a Web application).

A language addon is used to extend a language definition. It is also a language definition, and it shall be called /metainfo/zk/lang-addon.xml available to the classpath, or specified in WEB-INF/zk.xml.
