If you use thi mix:referencable MixinType the UUID of a node is kind of like primary key for this node. It is like a unique identifier. And you can use it to reference a node without knowing its path. That way you have 2 types of acces to specific nodes: - content structure aware via it's path - node identity aware via it's UUID It depends on the application which one is right or wrong. Think about the difference between identity and location. And now a mostly inappropriate comparison :) in a workshop you need a screwdriver so you go to the toolbox and look at the place where the screwdriver should be and take it, you won't look for a specific one, just the one you have in the toolbox; But in the checkroom you will want to have your specific jacket, that's why you get a unique number (at least for this evening) and even if they switch everything around in the checkroom, your number references exactly your jacket)) regards Christian
