Specify whether to include deprecated API in the documentation.

When the parameter is unselected (`false`), no deprecated API will be documented at all. This will also override the setting of "Generate | Cross-Reference Pages | Deprecated List" parameter, so no deprecated APIs list file and the "Deprecated" link in the navigation bar will be generated.

Default Value:

> The default value of this parameter is set according to the `-nodeprecated` option found on the Javadoc command line. When this option is specified, the default value is `false`, otherwise it is `true`.
