1. Instance inherit Instance Data Model, primitive type inherit Instance Type, Is it correct？
2. What is an Instance Type? How is it defined?

@suncpp "instance type" is an informal term that means the primitive type of the current part of the instance. In the instance:

{
    "foo": 3,
    "bar": "hello"
}

• The instance type of the whole instance is object
• The instance type of "foo" is number
• The instance type of "bar" is string

In the validation specification, some keywords only apply to certain instance types, and are grouped into sections accordingly.
