Take "XML" out of this, and everything you say is still true.
Synchronous RPC over a WAN is rough, no matter how it is encoded.  I
don't see any evidence at all that the RPC people wrap with XML is worse
than the crazy things people do with RMI and DCOM.

All of the issues you mention are important for *any* synchronous RPC
system.  Encoding is one of the least important issues in most cases, so
if you are implying that finding a less "fat" encoding will solve the
problems you mention, you are misleading people.
