     SPEC: Note that the SVG DOM 
     defines the attribute externalResourcesRequired as being of type SVGAnimatedBoolean, whereas the 
     SVG language definition says that externalResourcesRequired is not animated. Because the SVG 
     language definition states that externalResourcesRequired cannot be animated, the animVal will 
     always be the same as the baseVal.
