Makes sense. But that also means you're storing the data twice, which 
makes updates a bit of a pain. Do you send the XML documents so often 
that the performance gain of having them cached is worth the update 
pain? Or do you only store data as XML that is never updated?

Also, did you consider using a native XML database as a way to store the 
data? That would allow you to store it as XML and query it without 
having to break out fields for storage in relational columns.

Actually, I meant that it didn't strike me as likely that sending XML 
documents was the *only* thing you would do. I'm not at all surprised 
that it's one of the things you do.
