If you want to refer to Standard Arabic, use "ar". If Standard Arabic
has a Sudan-specific variant (dialect or spelling differences), then use
ar-SD. If what is intended is the vernacular Sudanese Spoken Arabic
(perceived as a distinct language from Standard Arabic or the spoken
varieties in other countries), then ISO 639-3 will provide a distinct
alpha-3 ID, and I suggest that people wait to use that.
