title: Setting the capability for aws cloudformation template-validate
body: <p>I am trying to validate a Cloudformation template. The command I am issuing is:</p>
  
  <pre class="lang-none prettyprint-override"><code>▶ aws cloudformation validate-template --template-body file://template.json
  </code></pre>
  
  <p>The response I am getting, however, is:</p>
  
  <pre class="lang-none prettyprint-override"><code>"CapabilitiesReason": "The following resource(s) require capabilities: 
    [AWS::IAM::Role]", 
  </code></pre>
  
  <p>I can't find any way to set the capability unfortunately.</p>
  
  <p>How do you set the capability?</p>
