Thread:User talk:Siebrand/Additional version of Nynorsk (nn)?/reply (3)

It could be used for instance at the Nynorsk Wikipedia (since we already for a long time have had articles written in Høgnorsk there, it would be a natural place to use it), but naturally also for any non-Wikimedia wiki that so wishes it; like the example I provided (I asked at the place if they could be interested in this).

I do not think that it has its own ISO 639-3 code (it does though seem to have been regisetered at IANA as nn-hognorsk, if that matters); however, the reason that I mentioned the formal versions of languages, is because I was thinking of Høgnorsk in the same manner: a subset of Nynorsk. What is the reasoning for allowing formal versions; and in which manner would this reasoning collide with the reasoning for allowing a more or less well-defined subset of an existing language?
