Catalog lookup is enabled to prevent requests to third party servers, and the third party schema referenced in the WSDL references multiple schemas in the same namespace.

When schema validation is enabled, the algorithm in org.apache.cxf.wsdl.EndpointReferenceUtils.SchemaLSResourceResolver#resolveResource does not resolve the correct schema since in the above scenario it falls back to namespace-only resolution, which returns the first schema it sees.  This can be fixed by trying to resolve on only the "filename" before resorting to namespace-only resolution.
