/**
 * This {@link WadlGenerator} adds all doc elements provided by {@link ApplicationDocs#getDocs()}
 * to the generated wadl-file.
 * 
 * The {@link ApplicationDocs} content can either be provided via a {@link File} reference
 * ({@link #setApplicationDocsFile(File)}) or
 * via an {@link InputStream} ({@link #setApplicationDocsStream(InputStream)}).
 * 
 * 
 * The {@link File} should be used when using the maven-wadl-plugin for generating wadl offline,
 * the {@link InputStream} should be used when the extended wadl is generated by jersey at runtime, e.g.
 * using the {@link WadlGeneratorConfig} for configuration.
