	<component-name>area</component-name>
	<component-class>org.zkoss.zul.Area</component-class>
	<widget-class>zul.wgt.Area</widget-class>
	<mold>
		<mold-name>default</mold-name>
		<mold-uri>mold/area.js</mold-uri>
	</mold>
</component>
<component>
	<component-name>bandbox</component-name>

	</annotation>
</component>

component-name

[Required]

The name of the component. It must be unique in the whole language.

extends

[Optional]

It specifies whether this definition is extending from another definition. If omitted, it is considered a definition of a new component. If specified, it extends from the given component definition (which must be defined first).

Notice that the component's name could be the same as the definition it extends from. If the same, the existent definition is simply overriden (no new component definition is created). It is a useful technique to change a component definition, such as adding annotation, providing the initial properties and so on.

component-class

[Required if no extends]

It specifies the component's Java class at the server side. It is required if you define a new component.
