Everywhere I look, it says it drops earlier versions of IE, but doesn't say whether we are automatically buying into HTML5 compatible browsers only.  We are using Angular (latest) and I was just told a few days ago that we are NOT relying on the new HTML5 tags (like email).   Yet, we are using jQuery 2.1.0 in the solution.  Also, the Angular-xeditable we are also using wraps the HTML5 tags nicely.  

So, does our use of jQuery 2.1.x imply we are only supporting an HTML5 compatible browser anyway  with support for things like email tags or maxlength on textarea elements, or should we not rely on those HTML5 conventions (as I was told) and use other workarounds?
