Topic: ordinalValue extension should include the expansion too
Eric Haas (Feb 01 2019 at 02:07):
Add context of ValueSet.expansion.contains to ordinalValue extension
Eric Haas (Feb 01 2019 at 02:11):
My use case is a contained VS on a Questionnaire. Example here: https://argonautproject.github.io/questionnaire/Questionnaire-questionnaire-example-phq9.xml.html
need to have ordinal values in the expansion too values when referenced from Questionnaire.item.answerValueSet in order to do scoring.

@GG can this be a technical correction??? Otherwise SDC and I need to come up with an extension.
Lloyd McKenzie (Feb 01 2019 at 02:18):
Can a derived model add additional contexts? I'm not sure if that's a safe thing to do or not...
Eric Haas (Feb 01 2019 at 02:21):
I don't know what you mean?
Eric Haas (Feb 01 2019 at 02:26):
Questionnaire.item.option is going to have n extension to indicate a display order so if that need exists there it will exist for the contained values too.
Lloyd McKenzie (Feb 01 2019 at 02:36):
SDC could create a derived profile of the existing extension and add extra contexts while keeping the URL the same. The question is whether that's legal
Grahame Grieve (Feb 01 2019 at 03:42):
it needs to be legal for a IG to extend the use of an extension somehow
Lloyd McKenzie (Feb 01 2019 at 03:45):
I can't really think of a downside of someone saying "you know that extension that X defined, I think it's appropriate to use in Y too". I mean, it's possible someone could use something inappropriately, but really all we'd be doing is forcing them to use a custom extension inappropriately instead.
