ref contextualisation

Is there any way to contextualise a $ref?

When we want to use a ref to define a property, we are not able to define any other attributes but $ref. It could be interesting to allow to include a description just for the property.

For example, if we define an "Amount" (currency + decimal) and we use it in several places, we could want to explain the meaning of this specific property (e.g. currentBalance, overdraft...)

Is there any way to do this without creating a new schema just for one property?
