To the extent that you minimize the negotiation, you win.  This is true 
on several levels.  First, to the extent that the data is 
self-documenting and doesn't require callouts to schemas, format 
converters and so on, you remove failure points.  Second, to the extent 
that you have to agree on these things, it slows you down.  Very 
significant systems (for example, more than one of the big 
general-purpose portals) have XML-mediated systems where they sorted 
things out by emailing examples back and forth.
