Angular 2 - FormControl setValue 'onlySelf' parameter
<p>Trying to understand what the 'onlySelf' parameter does when passing to setValue.</p>

<pre><code>this.form.get('name').setValue('', { onlySelf: true })
</code></pre>

<p>The documentation says: "If onlySelf is true, this change will only affect the validation of this FormControl and not its parent component. This defaults to false."</p>

<p>However I'm struggling to understand this. Still fairly new to the using Angulars' model driven forms.</p>
