If the two applications are on different machines, then the document needs
to be serialized to be sent from one to the other. For nearly all practical
purposes, the best serialization format for XML documents is... XML.

The Java serialization of a DOM is going to be vastly less efficient than
the XML representation.

That's a requirement on the transport layer, which is quite independent of
the message syntax chosen.
