Payload branch "attributes"

The first "branch" of the payload is made of those informations that are relative to the cart/checkout/purchase only, and for some reason they cannot be easily grouped into other "scoped branch".

Let's review an example:

{
  "context": "...",
  "event": "...",
  "checkout_step": "...",
  "attributes": {
    "id": 298,
    "lang_id": "it",
    "availability_mode": "master",
    "currency": {
      "id": 1,
      "name": "Euro",
      "iso_code": "EUR"
    },
    "products_total_qty": 2,
    "total": "84.96",
    "total_cart_discount": "0",
    "total_discount": "0",
    "total_taxes": "15.32",
    "total_products": "539.95",
    "total_products_real": "84.96",
    "total_products_discount": "454.99",
    "total_shipment": "0",
    "total_payment": "0"
  },
  "products": [...],
  "carrier": {...},
  "payment": {...},
  "delivery": {...},
  "billing": {...},
  "user": {...},
  "engagements": {...}
}
