I found a couple of sentences in STU3 that seem to be contradictory:
"The update interaction creates a new current version for an existing resource or
creates an initial version if no resource already exists for the given id."
"If no id element is provided, or
the value is wrong, the server SHALL respond with an HTTP 400 error code, and SHOULD
provide an OperationOutcome identifying the issue."
What does "wrong" mean ?
Thank you for the help!
