Topic: Modifier extension safety

It is unsafe to ignore a modifier externsion. What if we do not understand the extension then is it better to ignore the whole resource than to process it without understanding it? (a question from the fhir cert review class - thanks!)

In my course I usually present a few options:
- reject the instance
- reject the piece of the instance containing the modifier (e.g. if there's a modifier saying 'do not contact' a patient contact, and you don't care about contacts at all, then just throw it away)
- just display the narrative
- show the resource with a flag warning the user that it might not actually apply
- hold the resource for human review (only works in asynchronous situations)
What makes sense will depend on where the modifier appears and what the application is trying to do
