// typed.Node is a superset of the ipld.Node interface, and has additional behaviors.
//
// A typed.Node can be inspected for its typesystem.Type and typesystem.Kind,
// which conveys much more and richer information than the Data Model layer
// ipld.ReprKind.
//
// There are many different implementations of typed.Node.
// One implementation can wrap any other existing ipld.Node (i.e., it's zero-copy)
// and promises that it has *already* been validated to match the typesystem.Type;
// another implementation similarly wraps any other existing ipld.Node, but
// defers to the typesystem validation checking to fields that are accessed;
// and when using code generation tools, all of the generated native Golang
// types produced by the codegen will each individually implement typed.Node.
