* `tags: List[str] = []` has a default of an empty list: `[]`.

but you might want to omit them from the result if they were not actually stored.

For example, if you have models with many optional attributes in a NoSQL database, but you don't want to send very long JSON responses full of default values.

### Use the `response_model_exclude_unset` parameter

And it will be annotated / documented accordingly too.

## Nested Models

Each attribute of a Pydantic model has a type.

But that type can itself be another Pydantic model.

So, you can declare deeply nested JSON "objects" with specific attribute names, types and validations.

All that, arbitrarily nested.

### Define a submodel

  // destroy an instance of this class.
  virtual void Release() = 0;

  // Creates an operation builder and ties it to this context.
  // The returned object can be used for setting operation's attributes,
  // adding inputs and finally executing (immediately or lazily as in tracing)
  // it in this context.
  virtual AbstractOperation* CreateOperation() = 0;

	flag.StringVar(&name, "name", "", "attribute name or it can be a wildcard if '.' is specified")
	flag.Uint64Var(&value, "value", 0, "attribute value expects the value to be uint64")
	flag.BoolVar(&set, "set", false, "this is a set attribute operation")

	flag.Parse()

	if set && value == 0 {
		log.Fatalln("setting an attribute requires a non-zero value")
	}

    }

    // POST /api/admin/user/setting
    @Execute
