Once you have your data packaged as XML documents, you need to select a
protocol for exchange of the information between applications.

For async transmission, the XML document can be packaged in a MIME message
and transmitted via SMTP. For sync transmission the XML can be packaged in a
MIME message and transmitted via HTTP. You can also define a custom protocol
and pass the data via for example a socket.

Whether or not you need to define a DTD for the messages and/or validate the
messages at each end depends on the needs of your application.
