Topic: source-list-mode only_one

The description of "only_one" in https://www.hl7.org/fhir/valueset-map-source-list-mode.html is currently defined as "Only process this rule is there is only item". That would imply for me that you are supposed to skip the element if it's repeating. However the mapping language tutorial contains a comment saying that the engine is supposed to throw an error: https://www.hl7.org/fhir/mapping-tutorial.html#step6
What would be the preferred way of handling only_one?

In the .NET implementation I've now chosen to skip the rule and not throw an error

I think it should be an error - the user has only allowed for one here. Silently ignoring it kind of my worst case outcome
