title: Angular directives - element or attribute?
body: <p>I'm part of a team with about 6 UI devs, of varying quality and next to no Angular experience. Many are contractors, with little experience with the code base. The app has a very fancy (complicated) UI. It supports IE8+ (soon hopefully IE9+).</p>
  
  <p>We're introducing Angular for a major extension to the app, and I've been asked to write guidelines on the use of Angular for the team.</p>
  
  <p>We'll use directives to create fancy UI elements, all prefixed with "ipwr" to avoid name clashes. I'm trying to decide whether to mandate that devs give their directives the restriction "element" or "attribute". Mandating only one, to avoid chaos and confusion.</p>
  
  <p>My question is: what restrict is better or more popular for directives, "element" or "attribute"? 
  My main concern is ease of use for people with little Angular experience who are new to the application code base, to reduce bugs, copy and paste behaviour, etc.</p>
