Detecting functionality used in modules, where no explicit dependency is done

Having:

angular.module('app', ['bootstrap.ui', 'nganimate'])

and a submodule using this dependency

angular.module('app.submodule.subsub', []).directive(function($animate){
    $animate.start(...)..
})

How about having a dependency as well in e.g. a different arrow color?
Probably code of https://github.com/olov/ng-annotate
could be reused to support recognition of full injected modules.
