I have a section of a schema for a model that I need to parse. Lets say it looks like the following.

{
  type = "Standard";
  hostname="x.y.z";
  port="123";
}

The properties are:

1. The elements may appear unordered.
2. All elements that are part of the schema must appear, and no other.
3. All of the elements' synthesised attributes go into a struct.
4. (optional) The schema might in the future depend on the type field -- i.e., different fields based on type -- however I am not concerned about this at the moment.
