Validity of test DOM 2 HTML HTMLAppletElement 05

The test HTMLAppletElement 05 of DOM 2 HTML
http://www.w3.org/2004/04/ecmascript/level2/html/HTMLAppletElement05.html

is not much valid, I think.
The test checks if the value held by applet.codeBase is the same as  
declared in the page markup.
Both Opera and Mozilla resolver the src, href, data and codebase  
attributes for elements. Accessing these properties directly in DOM  
elements returns a resolved url, while accessing using getAttribute(..)  
returns the original value, also for the sake of using selectors.
Is there as part of the specification where these properties are required  
to be the original values ?
