Necessary Properties

With this support table, we want to illustrate, which properties can be removed from an object, and still create an appropriate response. We note that the basic form of an object is

{
    "type": "Note",
    "attributedTo": "http://pasture-one-actor/actor",
    "to": [
      "as:Public",
      "http://mitra/users/admin"
