Mapping of OTL language system tags to ISO 639 codes was not part of the 
original intent of the former, and I'm still not convinced it is a good 
idea, since they represent different types of data that only sometimes 
align. I certainly don't think it makes sense to use ISO 639 codes — 
which I think can only constitute an annotation to OTL language system 
tags — to determine the intent of the latter.

That said, in this case I don't imagine there are many fonts that would 
be affected by redefining SLA as North Slavey.

Getting Spiekermann to not like Helvetica is like training
a cat to stay out of water. But I'm impressed that people
know who to ask when they want to ask someone to not like
Helvetica. That's progress. -- David Berlow
