I was creating a Proof of Concept (POC) for using Service Broker (SB) to synchronize databases across an untrusted domain boundry. I wanted to validate my XML SB messages using an XSD based on the table definition. I first approached the problem from the standpoint of using VS2008 database edition, but then I found a simpler method by using the SELECT statement with the FOR XML clause. By adding the XMLSCHEMA qualifier the XML Schema definition is added to the payload, but because that's all I want I simply use the TOP 0 clause to suppress any actual data.
