20/** Test for Bug 694754 **/
21/*
22The following code tests if calling the DOM methods Document::lookupNamespaceURI
23and Document::lookupPrefix directly (with quickstubs) and through XPCOM leads
24to the same result.
25
26This test makes use of the bug/feature that deleting a method from the
27prototype forces the engine to go through XPCOM.
