If I look at the SchemaProps definition, I see that the ID is marshalled into json:

type SchemaProps struct {
	ID                   string            `json:"id,omitempty"`
}

Is there a specific reason for that? Because when I marshal the definitions to json, this ID is also added, but according to openapi the id field is not part of the spec and the validation in some validators fails.

Can we change that to json:"-,omitempty" or is there another way of marshalling the spec?
