Every node carries an id
A node without an id cannot be referred to by an edge, an exposure entry or a runtime result, so a workflow containing one is refused rather than stored.
The rule
Normative: this is the rule
- Every node in a workflow must carry a non-empty
id. - A node whose
idis absent or empty is refused, and because the node cannot be named the error identifies it by its position in the workflow's node list.
Rule identifiers are permanent and are never renumbered. Each implementation publishes its own standing against these rules; this specification does not.spec 1.0-draft · R5.c · changed in spec 1.0
