Feature: Core schema: id
  Scenario: absolute URI, single schema
    When the schema is:
      """
      {
          "title": "Test Schema",
          "id": "http://www.example.com/schemas/json"
      }
      """
    Then the id of "Test Schema" is "http://www.example.com/schemas/json"

  Scenario: relative URI, single schema
    I-D says: "If this schema is not contained in any parent schema, the 
    current URI of the parent schema is held to be the URI under which 
    this schema was addressed."

    I think this means that the id of the root schema is taken to be the 
    URI from which the schema was retrieved, i.e. schema validators are
    supposed to include an HTTP client, which seems a bit bonkers to me,
    or the client passes in the URI from where the schema was retrieved, 
    which is weird, but more palatable. The current implementation does
    neither of these, but I don't think it's too important at this point.
