================================ To-do: archetypes.schemaextender ================================ o Test, test, test! We need to find out when this breaks. ;) Investigate: ------------ o Explicit ordering of adapters (e.g. by interface specificity) o At the moment, users must subclass fields and mix in ExtensionField. We could either ship with or generate on-the-fly a field type for each of the standard Archetypes fields. However, we should have tests covering all fields in that case.
