<font face="georgia,serif">I agree with that summary, Doug. Just because V is registered doesn't mean that all "siblings" of V need to be registered.</font><div><font face="georgia,serif"><br></font></div><div>
<font face="georgia,serif">But for for the prefix model of BCP47 to work well, the obvious "parents" of V should be registered. For example, suppose that I wanted to register Beckmeier's orthography of Valley Girl English (as opposed to Tedesco's or Humphrey-Brookrock's). It doesn't mean that I need to have Tedesco's or Humphrey-Brookrock's registered also, but it does mean that I should register Valley Girl English, so that we can have en-US as a prefix for valygirl, and en-US-valygirl as a prefix for beckmeie.</font></div>

That is, we can't ever narrow a prefix, so we can't later register valygirl and have it be required for beckmeie.</span></div>

</div>Sorry, that was supposed to be:<br>
<div class="im"><br>
For any given language L with some variety that can be represented by<br>
</div>the variant subtag V, the tag "L" by itself, without the subtag 'V',<br>
