The SVGExternalResourcesRequired interface defines an interface which applies to all elements where this element or one of its descendants can reference an external resource.

Warning: This interface was removed in the SVG 2 specification.



Corresponds to the externalResourcesRequired attribute of the given element.

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


This interface doesn't implement any specific methods.
