An XML schema is pretty isomorphic to an object model, as in each element
type thingy is like a form of class. More work will be required to adapt
differing object models to the intervening XML if the object models
differ a lot, it doesn't really save anything in conversion overhead...

XSLT is itself a language, just like Java and friends, don't forget.

You can do the same with any data format! Ones that use the entire 0..255
byte range rather than stick to a subset will need escaping or base64ing
in SMTP, but IIOP and RMI are just more efficient ways of shifting bits of
data than FTP/SMTP/HTTP, they don't fulfill any special requirements of
the encoded data.
