Define a property as both Mandatory & Read-only
Currently, a property field can be either Mandatory or Read-only (and not both).
I'm proposing to enable property fields to be Mandatory and or Read-only.
We have come across instances where we would like to specify a Mandatory field (ie. Approval Date) as Read-only as once it has been entered by the end-user, it cannot be changed (unless done by the Library Administrator).
