NHibernate Intellisense for Visual Studio 2008

From the NHibernate distribution, I renamed nhibernate-mapping.xsd to nhibernate-mapping-2.2.xsd and nhibernate-configuration.xsd to nhibernate-configuration-2.2.xsd. Then I copied those two files to C:\Program Files\Microsoft Visual Studio 9.0\Xml\Schemas and immediately intellisense started working for me in Visual Studio 2008.
