Not sure what you mean by 'convert to w3c'. Do you mean serializing a JDOM
document to XML?

Having a standard like XML signature enables interoperability
between different implementations. If jdom-dsig is compliant, it will be able
to verify documents signed by other implementations, e.g. XML Security from
apache  (http://xml.apache.org/security/); and other implementations will
be able to verify documents signed by jdom-dsig. And of course, the suff that
jdom-dsig implements is compliant.

I cannot recall any. But the point of jdom-dsig is that if you work with XML
and JDOM and has a need to sign or verify XML Signatures, it would be very
convenient to do it directly for the JDOM Document.
