<p>
Obtain this value from the <code>VersionId</code> result of <a>DeliveryStreamDescription</a>. This value is
required, and helps the service perform conditional operations. For example, if there is an interleaving update
and this value is null, then the update destination fails. After the update is successful, the
<code>VersionId</code> value is updated. The service then performs a merge of the old configuration with the new
configuration.
