def attach_message(key, message):
  """Adds an attached message to the module definition.

  NOTE: This must be called within a `module_fn` that is defining a Module.

  See ModuleSpec.get_attached_message() for an introduction to attached messages
  and the API for module consumers.

  To define a new type of attached message:

    * Select a reasonably descriptive name as a unique key. For now, keys must
      be valid Python identifiers that start with a letter. Punctuation besides
      underscores ('_') is reserved for future use in hierarchical names.

    * Define a Protocol Buffer message type to store the value for the key.
      (Use generic containers like google.protobuf.Value only if running
      the protocol compiler is infeasible for your build process.)

    * For module consumers, consider providing a small library that encapsulates
      the specific call to get_attached_message() behind a higher-level
      interface and supplies the right message type for parsing.

  Attached messages work best for few messages of moderate size.
  Avoid a large number of messages; use repetition within messages instead.
  Avoid large messages (megabytes); consider module assets instead.

  For modules with multiple graph versions, each graph version stores separately
  what was attached from within the call to `module_fn` that defines its graph.

  Args:
    key: A string with the unique key to retrieve this message. Must start
      with a letter and contain only letters, digits and underscores. If used
      repeatedly within one invocation of `module_fn`, then only the message
      from the final call will be returned by `get_attached_message()`.
    message: A protocol message object, to be stored in serialized form.

  Raises:
    ValueError: if `key` is not a string of the form of a Python identifier.
