/**
 * A Staves document as BPMN 2.0 XML, per spec/MAPPINGS.md, with a diagram so it opens drawn in BPMN tools.
 *
 * Tracks are lanes; an outside track is its own pool, and what passes to or from it is a message flow.
 * A job is a user task for a person and a service task for an agent or a system; a job with tasks is a
 * collapsed sub-process drawn on its own page. An artifact handoff is a sequence flow plus a data object; a
 * store is a data store. Exits leave through an exclusive gateway; a gate is a user task for whoever answers
 * for it, before that gateway. The result is a description, never an executable process
 * (isExecutable="false"). What BPMN has no place for — provenance, disputes, outcome — is kept as
 * documentation and staves: extension elements.
