title: ec2 describe-account-attributes - Is the result for the entire account or for regions within an account?
body: <p>What does the output of <code>ec2 describe-account-attributes</code> exactly represent?
  I see this object in there,</p>
  
  <pre><code>{
              "AttributeName": "max-instances",
              "AttributeValues": [
                  {
                      "AttributeValue": "20"
                  }
              ]
          }
  </code></pre>
  
  <ol>
  <li>Is <code>"AttributeValue": "20"</code> for the entire account cumulatively or for every region separately?</li>
  <li>Also, if I request for the limit to be increased does the increased limit apply to all the regions or do I have to specify the region?</li>
  <li>I read somewhere that the limits apply to specific instance types separately which confuses me even more about the output of this method</li>
  </ol>
