> This bug affects endpoints, which have schema validation enabled and also contain a wsdlLocation.
If a schema of the WSDL holds a reference to a DTD, the resolution of the DTD fails. These
results in the fact that schema validation is repealed. This issue has already been raised
on the mailing list (cf. http://cxf.547215.n5.nabble.com/SAXException-resolving-resource-http-www-w3-org-2001-XMLSchema-dtd-td551217.html
and http://cxf.547215.n5.nabble.com/SAXException-resolving-resource-http-www-w3-org-2001-XMLSchema-dtd-td3200050.html
, respectively).

not possible to check this error with any asserts on the client side. However, you will see
the stacktrace raised by the service.
