It is unclear how to use Medication.amount.

Since Medication.package has been removed from Medication in R4, I assume the intent is to roll up different package sizes of the same Medication into one instance of Medication and move the information about the package size to MedicationRequest.dispenseRequest.amount and MedicationDispense.amount.

However, it in not clear how to use Medication.amount in this scenario, since it still refers to the "amount in package" even though the Medication resource is no longer tied to one package size.

To clarify:

Assuming there are 3 package sizes of "Bayer Aspirin 500", with 10, 25 and 50 tablets, I would assume they are all represented by the same Medication "Bayer Aspirin 500".

In this scenario, what would the Medication.amount be?
