I want to know the answer to the following question:
Who is exempt from the standard and uses their own?
All the background I'm provided with is that "The AVL, created by the Valencian parliament, is in charge of dictating the official rules governing the use of Valencian, and its standard is based on the Norms of Castelló (Normes de Castelló).". Is that enough to answer the question?
Answer: no
