The text said a directive wouldn't work out of the box as an element, but the note immediatelly
below says that by default the directives restrict to elements or attributes.

11f5aee made the removed comments invalid.

feat($location): add ability to opt-out of <base/> tag requirement in html5Mode

This feature allows disabling Angular's requirement of using a <base/> tag
when using location in html5Mode, for applications that do not require
using $location in html5Mode in IE9. To accomplish this, the $locationProvider.html5Mode 
method has been changed to accept a definition object which can optionally set a 
requireBase property to false, removing the requirement of a <base> tag being present
when html5Mode is enabled.

BREAKING CHANGE: The $location.html5Mode API has changed to allow enabling html5Mode by
    passing an object (as well as still supporting passing a boolean). Symmetrically, the
    method now returns an object instead of a boolean value.

    To migrate, follow the code example below:

    Before:

    var mode = $locationProvider.html5Mode();

    After:

    var mode = $locationProvider.html5Mode().enabled;

Fixes #8934
