Apart from this they are exactly the same. Older "ws-security-" values continue to be accepted in CXF 3.1.0. To use any of the configuration examples in this page with an older version of CXF, simply add a "ws-" prefix to the configuration tag.</p><h1 id="JAXRSXMLSecurity-XMLSignature">XML Signature</h1><p><a shape="rect" class="external-link" href="http://www.w3.org/TR/xmldsig-core/" rel="nofollow">XML Signature</a> defines 3 types of signatures: enveloped, enveloping and detached.
