<p>
The base validation domain that will act as the suffix of the email addresses that are used to send the emails.
This must be the same as the <code>Domain</code> value or a superdomain of the <code>Domain</code> value. For
example, if you requested a certificate for <code>site.subdomain.example.com</code> and specify a
<b>ValidationDomain</b> of <code>subdomain.example.com</code>, ACM sends email to the domain registrant,
technical contact, and administrative contact in WHOIS and the following five addresses:
</p>
<ul>
<li>
<p>
admin@subdomain.example.com
</p>
</li>
<li>
<p>
administrator@subdomain.example.com
