Adding HTML5 Validation and Intellisense

I am trying to create an HTML5 web page in Visual Studio 2010 according to the information at the following link
I followed the instructions below and changed it from  "XHTML 1.0 Transitional" to "HTML5". I have a number
of websites. Will this cause problems with my other projects? Is this a general setting that now governs all the sites I build?

You will definitely want to make sure you have Service Pack 1 installed! By installing Service Pack 1 you get both intellisense (can’t live without that anymore) and validation for HTML5. Don’t forget after you install Service pack 1 to go to Tools | Options | Text Editor | HTML | Validation and set the validation to HTML5 or XHTML5 or the HTML5 validation won’t work.
