Though, having said that, the way you represent the data is different
in a relational database from the way you'd represent it in an XML

I'd suspect that the semantic nature of the queries people
make will be similar, but in databases it will be represented in a
manner that is easy to retrieve using SQL, while in XML documents it
will be represented in a manner that is easy to retrieve using XPath.
