	Payload []byte `protobuf:"bytes,3,opt,name=payload,proto3" json:"payload,omitempty"`
}

A URN along with a parameter object whose schema is determined by the URN.

This structure is reused in two distinct, but compatible, ways:

  1. This can be a specification of the function over PCollections that a PTransform computes.
  2. This can be a specification of a user-defined function, possibly SDK-specific. (external to this message must be adequate context to indicate the environment in which the UDF can be understood).

Though not explicit in this proto, there are two possibilities for the relationship of a runner to this specification that one should bear in mind:

  1. The runner understands the URN. For example, it might be a well-known URN like "urn:beam:transform:Top" or "urn:beam:windowfn:FixedWindows" with an agreed-upon payload (e.g. a number or duration, respectively).
  2. The runner does not understand the URN. It might be an SDK specific URN such as "urn:beam:dofn:javasdk:1.0" that indicates to the SDK what the payload is, such as a serialized Java DoFn from a particular version of the Beam Java SDK. The payload will often then be an opaque message such as bytes in a language-specific serialization format.
