Josh, Yes, I am trying to develop the service that is language and platform neutral, so I'm trying to find the "right" way to handle attachments. Unfortunately I don't have other platforms to test on.
The W3C WSDL 1.1 Note shows a MIME binding that supports attachments, but poking around on the Xmethods website, I didn't run across any WSDL that shows the MIME binding. If vender interoperability for attachments just isn't there yet, that would be good to know.
