For example, the form element (http://www.w3.org/TR/html5/the-form-element.html#the-form-element ) define property of type HTMLFormControlsCollection. Named child element of the form can be accessed via form.elements.namedItem('child-id'). The specification do not clarify, whether the shadowed named child element should be accessible in such way. 90867 1 dglazkov 2013-07-17 20:05:36 +0000 These normative requirements need to be removed from the spec. They are confusing to implementers, test writers and developers. Duping against bug 20139. *** This bug has been marked as a duplicate of bug 20139 ***
