title: What are supported device attributes on iOS during enrollment phase?
body: <p>I'm installing configuration profile using over-the-air (OTA) enrollment. What are supported device attributes on iOS during first phase payload?
  I'm sending sth like:</p>
  
  <pre><code>&lt;plist version="1.0"&gt;
      &lt;dict&gt;
          &lt;key&gt;PayloadContent&lt;/key&gt;
          &lt;dict&gt;
              &lt;key&gt;Challenge&lt;/key&gt;
              &lt;string&gt;challenge&lt;/string&gt;
  
              &lt;key&gt;DeviceAttributes&lt;/key&gt;
              &lt;array&gt;
                  &lt;string&gt;UDID&lt;/string&gt;
                  &lt;string&gt;DEVICE_NAME&lt;/string&gt;
                  &lt;string&gt;VERSION&lt;/string&gt;
                  &lt;string&gt;PRODUCT&lt;/string&gt;
                  &lt;string&gt;MAC_ADDRESS_EN0&lt;/string&gt;
                  &lt;string&gt;IMEI&lt;/string&gt;
                  &lt;string&gt;ICCID&lt;/string&gt;
              &lt;/array&gt;
  
              &lt;key&gt;URL&lt;/key&gt;
              &lt;string&gt;https://my-profile-server&lt;/string&gt;
          &lt;/dict&gt;
          &lt;key&gt;PayloadDescription&lt;/key&gt;
          &lt;string&gt;Enter device into the encrypted profile service&lt;/string&gt;
          &lt;key&gt;PayloadDisplayName&lt;/key&gt;
          &lt;string&gt;Profile Service&lt;/string&gt;
          &lt;key&gt;PayloadIdentifier&lt;/key&gt;
          &lt;string&gt;com.xxx.mobileconfig.profile-service&lt;/string&gt;
          &lt;key&gt;PayloadOrganization&lt;/key&gt;
          &lt;string&gt;XXX&lt;/string&gt;
          &lt;key&gt;PayloadType&lt;/key&gt;
          &lt;string&gt;Profile Service&lt;/string&gt;
          &lt;key&gt;PayloadUUID&lt;/key&gt;
          &lt;string&gt;1a21d4dd-6723-45c5-a184-c3fe0075db14&lt;/string&gt;
          &lt;key&gt;PayloadVersion&lt;/key&gt;
          &lt;integer&gt;1&lt;/integer&gt;
      &lt;/dict&gt;
  &lt;/plist&gt;
  </code></pre>
  
  <p>Is there any more attribute that I can get from the device in this payload? For example serial number? Is there any official list of possible attributes?
  Any help would be much appreciated. Thanks.</p>
