List Version Source flow Name there Why this flow
EF 3.1 fe0acd60-3ddc-11dd-9fe4-0050c2490048 1-pentene The consensus list is built from this one, so this row is the flow itself rather than something matched to it.

Every implementation that says anything about this flow. Published as is what this list did with the row: where more than one implementation states a number and they agree it publishes it as agreed; where only one speaks, as sole; where they disagree it publishes nothing and asks.
