Description

CC herohde

The "impulse" transform was discussed and introduced in some contexts, since an SDK with only splittable DoFn needs some way to get things moving, but we don't really have a central place where these specs live, except perhaps the proto comments.

TBD how best to address the fairly amorphous way these things are introduced and propagated.

Incidentally we have inconsistent version strings in the draft URNs in the Java codebase, so there's plenty that would also improve in technical quality by having more eyes on it.
