Regex Char Class Subtraction spec available [Kit George]

I propped the character class subtraction specification up on the BCL website:

https://www.gotdotnet.com/team/clr/bcl/TechArticles/techarticles/Specs/Regex/CharacterClassSubtraction.doc

This feature will be one of the many enhancements we make to Whidbey, so keep an eye out for it in Beta1.

Any feedback on the specification is appreciated!
