Need to remove ASF licenses from local copies of wsdl.xsd, http.xsd etc. and instead make these licenses available in trunk/distribution/src/main/release/licenses/, and reference them in ls distribution/src/main/release/NOTICE.
See mail thread subjected "Apache license in local copies of third party files?" on cxf-dev (started 03.10.2006).
Check why so many further copies of wsdl.xsd, http.xad etc are needed in tools modules (validator, wsdl2java).
