A formalism to enable connecting Field values to symbols would help a lot in data verification when checking dimensions.
Another point it is to do not only math (nexusformat/definitions#1084) with symbols, but also enable bool algebra. We could then express rules, like "If a>2 then b=3*a else b=1"
Such symbols could also be used not only for dimensions, but also min/maxOccurs.
