by that, I don’t someone working just on accessibility. Content may be authored using controlled language in a variety of contexts for a variety of reasons. Rather than doing something one-off in response to someone interested in accessibility, I’d want to
understand what the entire space looks like, what the various usage scenarios are, and from that whether one tag is enough, or whether there eventually need to be a set of tags with some systematic inter-relationships.<o:p></o:p></span></p>

<p class="MsoNormal">If the purpose is to distinguish webpages by BCP47 language tags, it is perfectly reasonable on a site to want to distinguish between a "normal" version, and a simplified version (not only for accessibility, but also for second-language

<p class="MsoNormal">Of the many thousands of languages that are encodeable with BCP47, almost none of them have a "precise definition". It is not productive to disallow a reasonably clear variant because it doesn't meet a standard <i>also not met by essentially
any of the primary language subtags.</i><o:p></o:p></p>
