Re: Variant subtag proposal: Høgnorsk variety of Norwegian

On the other hand... 

What fun... "In 1938, official Nynorsk went through a radical spelling reform. Today, the term Landsmål is used to refer to the pre-1938 versions of Nynorsk."

So Landsmål is synonymous with Nynorsk from 1929-1938, when new-Nynorsk diverged from it orthographically.
