Is it common/uncommon/unheard-of to have a 'valid' property:

Q_PROPERTY( bool valid READ isValid NOTIFY validChanged )

I'm thinking about classes like 'DeviceLocation' which would update with GPS changes, but at some point might just become invalid (or start invalid, until GPS turns on, etc).

So should isValid() only be used for 'typical' cases of, like default-constructed value-types, or is it fine as a property?
