Obtaining the SQL Server 2005 Report Builder XSD

I'开发者_StackOverflow社区ve managed to obtain the report definition schema for SQL Server 2005, but cannot find the xmlns:rd="http://schemas.microsoft.com/SQLServer/reporting/reportdesigner" schema anywhere.

Is it part of the 2005 install buried somewhere? The reason I ask is because I've recently started writing RDL files for SQL Reporting Services. I'd like to be able to validate both schemas and get autocompletion working (I'm using Eclipse mostly). Any Ideas on how I can get ahold of this xsd?

That's just an XML namespace - there's no physical representation of that, really. The rd namespace is part of the report definition stuff - should be in your XSD already.
