How to give intelligence into feature XML file

One day I was creating my feature file into solution package, at that time I saw that I didn’t get intelligence of all elements and attribute into my file and I have found that by adding below schema file, we will be having intelligence in any XML file. Though it’s very small things, but I thought to share with you.

Schema file:

"C:\Program Files\Common Files\Microsoft Shared\web server extensions\12\TEMPLATE\XML\wss.xsd"
