/**

 * <code>ServiceUIFactory</code> enables print services to provide additional

 * user interface dialogs.

 * <p>

 * A print service may provide a <code>ServiceUIFactory</code> implementation

 * if its <code>getServiceUIFactory()</code> method is called. If a factory

 * object is returned it can be queried for provided user interface dialogs.

 * Different roles are defined to denote dialogs providing informations about

 * the print service, dialogs for administration of a print service and for

 * end-user browsing dialogs.

 * </p><p>

 * The factory can support providing these UI roles in different dialog types

 * (AWT, Swing, JComponent, Panel). The support and use of Swing interfaces is

 * however preferred.
