I included "currently" in the quoted statement for a reason. AFAIK
there's limited cross-platform support for WS-Security currently
deployable, though there have been some demonstration hookups. Of
course, you can also get the same end-to-end message integrity and
selective data privacy using XML Encryption and XML Signature, which are
what WS-Security wraps. I'm not saying that these functions aren't very
valuable - only that SOAP at present adds very little value beyond the
underlying XML technologies.
