docs: Given a DMNNode, compute the proper name of the node, considering DMN-Imports.
  For DMNNode in this current model, name is simply the name of the model.
  For imported DMNNodes, this is the name with the prefix of the direct-dependency of the import `name`.
  For transitively-imported DMNNodes, it is always null.
