      implements org.richfaces.ui.common.AjaxOutput

  Focus component allows to set focus based on validation of components or alternatively it can preserve focus on currently focused form input.

  Focus can be bound to form (in case of placement to h:form) or to whole view (when placed outside of forms) - in latter case, all forms will be managed by one Focus. There can be at most one Focus per form. When there is one view-scoped Focus and form defines own Focus, form-scoped Focus settings will be used.

  Focus is applied each time the component is rendered - for each full page submit and for each partial page request (in case of ajaxRendered=true). Alternatively, you can use JavaScript API: `applyFocus()` function will immediately cause.
