Interested in XML Indexing in SQL 2005, read this
My buddy Shankar pointed me to this on XML indexing. It's an interesting topic since figuring out smart ways to index and search XML is a tough job.
Here's the paper: http://www.vldb.org/conf/2004/IND5P2.PDF
It talks about compression, tokenization, path indexing, etc, etc. If you're serious about XML and SQL Server 2005, you should read this paper.
Enjoy!
