<p>Hello,</p>
<p>in the draft of Werner Koch about WKD there is this paragraph:</p>
<pre>There are two variants on how to form the request URI: The advanced
and the direct method. Implementations MUST first try the advanced
method. Only if the required sub-domain does not exist, they SHOULD
fall back to the direct method. [1]</pre>
<p>I think it needs to be clarified what it means that the
sub-domain doesn't exist. If a server doesn't offer this
sub-domain, it doesn't exist .. check. But what, if it does offer
this sub-domain and the server isn't available for some reason?
Does that case count as "does not exist"?<br>
</p>
