How to suppress specific CSS 2.0 validation errors in Visual Studio 2008?

Question

A typical CSS property that I use often is overflow-x and overflow-y. Sometimes I use CSS 2.1 or later properties or selectors. These (correctly) raise a validation error:

Validation (CSS 2.0): 'overflow-y' is not a known CSS property name.

For years I ignored this, but it kinda feels wrong. It's possible to switch off warning in C# and other languages for a particular line, block, file or project. Is something similar possible for CSS (or HTML) errors or warnings? Instead of switching it all off, I prefer a more granular solution.
