Maven plugin extendedSoapHeaders option not under defaultOptions

For the Maven plugin[1], the extendedSoapHeaders option (used for implicit soap headers[2]) works only under the wsdlOption element, not the defaultOptions element (as shown in Example #3 on [1]) as it also should. Placing the extendedSoapHeaders command-line equivalent in defaultOptions:

<extraargs><extraarg>-exsh</extraarg><extraarg>true</extraarg></extraargs>

does work, however.
