Review Comment:
Is there a particular reason for moving these properties to class member
variables? In general, it is best to keep that as method-local variables unless
there is some other reason to move them around.

Review Comment:
Property Names cannot be changed with introducing an automated migration
method, or following a deprecation process. In general, the display name and
property name should match for new properties, so these property name changes
should be reverted.

Review Comment:
Instead of declaring instances of `AllowableValue`, it would be helpful to
define an enum of options that implemented `DescribedValue`.
