Attributes

Attributes include additional information related to an element, can be either required or implied (optional), and might have a default value. For example, an element might be a car with soundsystem, transmission, and doors as attributes. Soundsystem can be any text and is required; transmission is required because there is a default listed; other is optional.This would be expressed this way:

<!ELEMENT car>
<!ATTLLST car 
		soundsystem		CDATA	#REQUIRED
		transmission		(automatic | manual | 5-speed-manual) "automatic"
		other				CDATA	#IMPLIED>

Attributes are always mapped to component fields and are related directly to elements. The component field within Siebel application has the XML Style property set to Attribute.
