Suggested approach for SPR-11532

Enable use of registered suffix match in the MVC XML namespace, see:

https://github.com/spring-projects/spring-framework/blob/12c393eb6d9ef0b67741eb3ef281922596f78811/spring-webmvc/src/main/resources/org/springframework/web/servlet/config/spring-mvc-4.0.xsd#L56-L61

The same effect can be achived with other styles of
Spring MVC configuration.
