MVC data annotation to compare one property to another?

Question

I've been playing around data annotations in MVC2 and am curious if there is an annotation to compare 2 properties (ie. password, confirm password)?

There's not one built in, however, you can make your own. See this link, which shows the "PropertiesMustMatchAttribute" that does just what you're looking for.
