Specify whether to show the default value of the element content.

The default value is provided by the 'default' attribute of the XSD element that declares the element component. For example:

<xs:element name="Language" type="LanguageType" default="English"/>
When the element (with simple content) is declared by reference, its default value may be specified both in the local reference component (which is being documented here) and in the global (referenced) element component. In that case, the actual default value will be looked for, first, in the reference component and, then, in the global one.
