Write this value to the specified output `stream` and return a reference to the modifiable `stream`. Optionally specify an explicit `version` format; by default, the maximum supported version is written to `stream` and used as the format. If `version` is specified, that format is used, but _not_ written to `stream`. If `version` is not supported, `stream` is left unmodified. (See the package‐group‐level documentation for more information on `bdex` streaming of container types).
