Some people (including the authors of NHibernate In Action book) say that in order to enable IntelliSense for XML files in Visual Studio (for example for Wix, NHibernate or Spring.NET) you need to copy corresponding XSD files to Program Files\Microsoft Visual Studio 9.0\Common7\Packages\schemas\xml
This is not accurate. Correct location is Program Files\Microsoft Visual Studio 9.0\Xml\Schemas\
