All possible types of let elements declared inside a declarations trait

A workflow script running in the Mobilengine Cloud would access the submission of the webform above in the format below:

{...
  boxQ: {text: "giant"},
  boxR: {text: "shrimp"},
  selectedKey: {pitter: "giant", patter: "shrimp"},
  selectedText: "Goo!",
  selectedValue: {pitter: "giant", patter: "shrimp", potter: "Goo!"},
  scalarLet: "shrimp , giant",
  recordLet: {pitter: "giant", patter: "shrimp"},
  tableLet: [{patter: "giant"}, {patter: "shrimp"}],
...}

See the workflow script reference guide for more details on data type mapping.
