How to Update Visual Studio's "Cascading Style Sheet Version for Validation"

Question

In my Visual Studio 2010, the "Cascading Style Sheet Version For Validation" is targeting CSS version 2.1. How can I update VS to target CSS version 3?

Answer 1

I just downloaded and installed Mojtaba.kaviani's "CSS 3 Intellisense Schema" and now my VS2010 has Intellisense support for CSS3 validation.
