title: How to create reusable nested subform component using AngularJS 2
body: <p>I am using Angular2 to create a web application. I have several data entry screens where the user must input a postal address which is part of a larger data entry for entities like Company or Person. </p>
  
  <p>So naturally I would like to create an Address Form Component that could be reused as a subform and somehow embedded or included within larger forms. This seems like it should be possible but I haven't been able to create an example or find and example. I've tried to create a subcomponent that has a FormBuilder as an input, but this doesn't work. </p>
  
  <p>the problem for me is that I can't seem to successfully communicate the enclosing &lt; form > tag to my html template. </p>
  
  <p>Does anyone know of an approach for this?</p>
