	// work puts into effect.
	Policy bool `json:"policy,omitempty"`

	// own sponsor or budget, that together bring about one change.

	// OutputOf names the piece whose output this is: a document,
	// materials, a toolkit, a training delivered, an event.
	OutputOf string `json:"outputOf,omitempty"`

	// a baseline, a system or portal people use, an app, a study), not an

	// output, not a project.

	// Deliverable is, for a change of its own in a document with a
	// deliverable register, the code of the row that hands it over (D4):
	// a component project is work the document itself lists, never a
	// phase, a service or a theme renamed.
