action "within"
source The property in the input Record containing the nested data structure.

With an input record structured like:

    "username": "jbloggs",
    "dates": {
        "start": "2017-09-23"

the start date needs to be referred to inside a within Instruction:

    "action": "within",
    "source": "dates",
    "instructions": [
            "source": "start",
            "destination": "project-dates",
            "name": "start",
            "dateFormat": "yyyy-MM-dd"
        // ...
