>
> In the [Beam Runner AP|https://s.apache.org/beam-runner-api], transforms of 
> interest to runners are to be identified by URN.
> Currently, Java-based runners use `instanceof` checks to both override 
> transforms and to implement primitive transforms. This language and 
> SDK-specific behavior should be replaced by adding these URNs, and checking 
> them.
