+ * default list of rules defined by the GraphQL specification will be used.

+ * Each validation rules is a function which returns a visitor
+ * (see the language/visitor API). Visitor methods are expected to return
+ * GraphQLErrors, or Arrays of GraphQLErrors when invalid.
+ *
+ * Optionally a custom TypeInfo instance may be provided. If not provided, one
+ * will be created from the provided schema.
