Enabling IntelliSense in Visual Studio to author a custom feature easily

Inside the TEMPLATE directory there is a directory named XML that contains several XML schemas, including one named wss.xsd. If you associate this schema file with feature files such as feature.xml and elements.xml, Visual Studio will provide IntelliSense, which makes it much easier to author a custom feature. You may also copy these XSD files into C:\Program Files\Microsoft Visual Studio 8\Xml\Schemas\.
