CXF's @SchemaValidation annotation not effective on method level

Issue

• The annotation org.apache.cxf.annotations.SchemaValidation is defined with
  @Target({ ElementType.TYPE, ElementType.METHOD })

However, applying it to single methods of a web service has no effect. More precisely, the following tests lead to unexpected results:

- no annotation on class, annotation on method: the method-level annotation has no effect

- annotation on class, annotation on method (with SchemaValidationType.NONE for overriding the class-level annotation): the method-level annotation has no effect

• For testing, we used sample project and the following SOAP request that does not conform to the web service's schema because of the "x" attribute:

<soapenv:Envelope xmlns:soapenv="http://schemas.xmlsoap.org/soap/envelope/" xmlns:sam="http://redhat.com/">
   <soapenv:Header/>
   <soapenv:Body>
      <sam:foo x="y"/>
   </soapenv:Body>
</soapenv:Envelope>
