Notice that Angular automatically places `ng-scope` class on elements where scopes are
attached. The `<style>` definition in this example highlights in red the new scope locations. The
child scopes are necessary because the repeater evaluates `{{employee.name}}` expression, but
child scopes are necessary because the repeater evaluates `{{name}}` expression, but
depending on which scope the expression is evaluated it produces different result. Similarly the
evaluation of `{{department}}` prototypically inherits from root scope, as it is the only place
where the `department` property is defined.
