I am finding that if I have parameters whose names do not match the names of their definitions then I get Error: parameter <paramname> not defined in bundle.

E.g. with

  "definitions": {
    "regionnn": {
      "type": "string",
      "default": "New Zealand South",
      "minLength": 4,
      "maxLength": 24
    }
  },
  "parameters": {
    "region": {
      "definition": "regionnn",
      "destination": {}
    },
  },

I run duffle install ... --set region=nzsth and get Error: parameter region not defined in bundle
