Article on the XML Support in SQL Server 2005

I worked with Shankar to write this article on the XML Support in Microsoft SQL Server 2005 which has just been published on the MSDN XML Developer Center. I would be very interested in comments on how you see an application need for storing XML content in a relational database along with querying and working with this data. E.g. The ability to store WordML documents created from Office 2003.
