For Xml

Is it just me, am I crazy, or has anyone else noticed how the column name that is returned by SQL Server 2000 when using a for xml selection is always the same? It is a guid, but it's always the same guid. Look at the documentation, look at the examples, do a google for XML_F52E2B61-18A1-11d1-B105-00805F49916B. It's always the same! So much for 'guaranteed unique identifier' !
