How can I add new attribute to a feature (not cloning another feature)
I understand that GT's Feature model is quite conservative about feature
mutation. Changing attribute value is OK but not OK with adding attribute.
I am thinking of following steps:
- Make a new feture type instance with all attributes from the current
feature's feature type instance, and a new attribute I want to add
- Create new feature with the new feature type.
- Copy data from old feature to new feature
But this way breaks my goal: I can not use referene to old feature to refer to
the new feature (becuase they are completely different object)
Any help is appreciated
