-------------------------------------------

But what if both of the event-handlers are present and they do different things?

> A corresponding redundant event handler should be added to all components that use javascript events.  The event mappings are listed below.
>    OnClick -> OnKeyPress
>    OnMouseDown -> OnKeyDown
>    OnMouseUp -> OnKeyUp
>    OnMouseOver -> OnFocus
>    OnMouseOut -> OnBlur
>    OnDblClick -> OnKeyDown
>    OnMouseMove -> (no equivalent)
>    OnDragDrop -> (no equivalent)
> This is a change that would help support Section 508 requirements when using Myfaces:
> WCAG Priority 2 : Checkpoint 6.4/9.3 [priority 2]
> Section 508 : Section 1194.22 - Paragraph L
> This element uses a device-dependent event handler that does not have a redundant device-dependent event handler, as required by both the Section 508 and WCAG standards. This may be inaccessible to some users of assistive technologies who cannot trigger the event because, for example, they do not use a mouse. An event handler is a script that runs upon a specified event, such as when the mouse is clicked or is moved into a certain region of the page. Some event handlers produce purely cosmetic effects. But if an event handler results in some substantial information or function, such as displaying a pull-down menu, it is important that a redundant input mechanism be provided for this element. This is most commonly done by assigning a keyboard-based event handler for every mouse-based event handler. Further, event handlers should not rely on mouse coordinates, which prevents device-independent input. For scripts and applets, page authors should ensure that event handlers are input device-independent. For scripts, specify logical event handlers rather than device-dependent event handlers. Alternatively, page authors should remove the event handlers if they do not wish to add a redundant device-dependent one.
