Whenever I am passing request parameters to an HTTPService through mxml, the xml tags for those parameters is being hightlighted in Red by the editor with a message of "Cannot resolve symbol 'x'"

In the below example the tags for each one of the parameters below would be highlighted in red with the error message.

<mx:HTTPService id="testSvc" url="/project/test.xml">
    <mx:request xmlns="">
        <test1>test1</test1>
        <test2>{var_for_2}</test2>
        <test3>test3</test3>
        <test4>{var_for_4}</test4>
    </mx:request>
</mx:HTTPService>

the error shows up whether or not i have an xmlns attribute for request.
Note: If I change all the parameters so they start with "mx:" then I do not get error highlights from IDEA. The flex compiler doesn't seem to care either way.

Environment: Windows XP sp3,
Java 5,
Flex 2.0.1
