This was the idea in the core of my point. Databases are far more 
powerful then any XML library I've ever seen... not counting the XML 
databases, I suppose, which don't seem to be in the common use that 
relational databases are (and I don't know much about, except $$$). 
Don't decide on XML until you've eliminated relational databases, for 
instance. (In an experienced engineer's head, that elimination can be 
instantaneous, based on the knowlege and experience of the engineer. In 
a new programmer, it may take actual thinking.) Indeed, relational 
databases are almost as cross-platform and cross-language as XML is!

But if you *need* transferability and extensibility, you'll probably end 
up with XML. Databases don't just sit on a file system or get forwarded 
in email very well.
