In our system , DiagnosticOrder.Item has many attributes. Example, 1. Code 2. Name 3. Parent Code 4. Problem with the code 5. Automatically added code ... and many more.
Seems to me , it will be more appropriate to create a new resource here. I see that DiagnosticOrder.Item is a backbone element.
Question is , should I create a new resource or should I use extension here for DiagnosticOrder.Item?
I am more inclined to create a new resource - but not sure how to create one ? If I have to create one , can you please guide me to create a new resource ?
At the moment, creating your own resource is non-compliant, though you could profile the Basic resource. What you're looking for sounds like an extension to me, though you could also look at DataElement.
