Explaining the reasons behind some of XML datatype's limitations
If you use XML in SQL Server 2005, and especially if you use it in association with schemas, I suggest you read Brandon's recent blog post about the limitations that were placed on the XML datatype. Brandon is one of our developers and he's got first-hand information about the design decisions that lie behind those limitations.
On a different note, I know my contributions to this blog have been few and far between recently. There's no shortage of topics I'd like to address, just a shortage of time.
