I have read that the difference between
ng-* and data-ng-*
in Angularjs is, that you get valid HTML if you use data-ng-*. But why do I need that if I can declare the angular namespace in just one single line?
<html xmlns:ng="http://angularjs.org" ng-app>
Or is it just for validating with an HTML Validator?
Excuse my stupidity, but I'm really confused about this.
