CORBA does the same. IDL structure provides the same benefits as mentioned by you.
I personally tell clients that CORBA is not generally considered a
reasonable base technology for SOA because it tightly couples the client
to the server data model. I'm not aware of any way around this - am I
missing something?

One of the major justifications I give for the widespread use of XML as
the basis for message exchange in SOA is that the XML structure provides
decoupling between client and server data structures - each end is free
to work with the XML messages as they want, without concern over how the
other end works. That seems to me to be an important criteria for SOA
services.
