Reviewing the extraction logic page (into observations) http://build.fhir.org/ig/HL7/sdc/extraction.html#obs-extract
There is a comment (point 3) that the exension questionnaire-observationLinkPeriod is required. Don't know what that has to do with data extraction to create a new Observation, isn't that for searching for an existing observation?
(this is however correct for the pre-population side)

I think we were using it for create vs. Update - and to indicate whether extraction should occur. But agree it's questionable
Eric Haas (Jun 08 2019 at 15:32):
I understand it as a flag to say “extract me”. The presence of a code element alone does not mean extraction should occur. It could just be the code for that item.

So if you want to create an Obs. You could have the extension without a value right? I mean like 0 secods
Paul Lynch (Jun 10 2019 at 16:44):
@Eric Haas I suppose that would be one way to prevent prepoluation, if you just wanted the extraction behavior.
