+## Design Principles

+1. Maintainability
+1. Flexibility
+1. Cognitive simplicity
+1. Ease of de/serialization
+1. Ease of implementation
+
+These are the guiding principles behind the design of KDL, in order of
+importance. These principles will hopefully be useful in tie-breaking and

+for each one will be settled on as the project matures.
