Starting with the disambiguated Jevko grammar from the previous article1:

Value = *Subvalue Label
Subvalue = Label "[" Value "]"
Label = *Symbol
Symbol = Escape / %x0-5a / %x5e-d7ff / %xe000-10ffff
Escape = "\" ("\" / "[" / "]")

Any other shape is invalid Data Jevko.

The above description is expanded and formalized in this article.
