They would all govern: each notation's own processor would do whatever it
does and the processing application could use the result or not as it
pleased: a given data object can be many things at once.

Remember that notations do not affect the *parsing* of the data, only its
semantic interpretation. There is never a problem with having multiple
semantics associated with a data object as long as you know which one
applies to your process.
