[ARCHIVE] No x-min-v Header Provided

Question

How should a Data Holder  respond in the instance when no x-min-v header is submitted?

For example; a Data Holder supports versions 1 and 2 of their endpoint and a Data Recipient sends a request with x-v = 3; would they respond with a 406 error message or with the maximum version they support?

Answer

If no x-min-v header is supplied it means that the client only supports a single version specified in x-v so if the holder cannot supply that version then they should respond with a 406.

In the scenario you outline in your question you would supply a 406.
