/** Test for Bug 694754 **/

/*
|
|
The following code tests if calling the DOM methods Document::lookupNamespaceURI
|
|
and Document::lookupPrefix directly (with quickstubs) and through XPCOM leads
|
|
to the same result.
|
|
|
|
This test makes use of the bug/feature that deleting a method from the
|
|
prototype forces the engine to go through XPCOM.
