<GH>Right, but a new registration of a sign language in the future 
without registering the 'sgn' Prefix for it will risk to cause interop 
problems for that language, so that should not continuously be done. And 
if it is done, it should be corrected. And while it is in the process of 
being amended in the language registry, applications supporting that 
language could regard it to be a sign language anyway by application 
agreement.
So, I think we can live with it.
