//
// This is intended to be used to register these types with encoding
// packages that require registration of types used in interfaces, such as
// encoding/gob, thus allowing cty types and values to be included in streams
// created from those packages. However, registering with gob is not necessary
// since that is done automatically as a side-effect of importing this package.
//
// Callers should not do anything with the values here except pass them on
// verbatim to a registration function.
//
// If the calling application uses Capsule types that wrap local structs either
// directly or indirectly, these structs may also need to be registered in
// order to support encoding and decoding of values of these types. That is the
// responsibility of the calling application.
