W9999 Feature Under Development

Umple warning reported a feature is used that is not yet fully implemented in Umple

Features are often added to the syntax of Umple before they are added to the semantics and code generation. This is to ensure that adding the feature will not break existing code. If you receive this warning, then it means you are using such a feature. No code is yet generated from this feature, or else the generated code is incomplete.
