+        The implementation must validate the indices referenced by <code>drawArraysInstancedANGLE</code> and <code>drawElementsInstancedANGLE</code>
+        similarly to how indices referenced by <code>drawArrays</code> and <code>drawElements</code> are validated according to section
+        <a href="http://www.khronos.org/registry/webgl/specs/1.0/#ATTRIBS_AND_RANGE_CHECKING">Enabled Vertex Attributes and Range Checking</a> of the
+        WebGL specification.

     <p>
       Although the extension contains ANGLE in the name it may be exposed by any implementation, whether or not the implementation uses the ANGLE library.
