I've created a client side image map on the linked page which is used to navigate the map. (It's the controls in the upper left of the map.) In order to work correctly in Safari, I need to use the attribute "usemap='#map0_0'". But the XHTML validator complains about the presence of the '#'. If I remove the '#', it validates (and works in FireFox), but doesn't work in Safari.
