As this will be the second version of CDS hooks – we will have implementations on STU1 and STU2. We should address this in the document. Possible implementations of this could be:

• Include CDS Hooks and Hook version in CDS Service response.
• Have different end-points for this for each combinations. E.g. by including the CDS Hooks version in the cdssevices URL: {base-url}

  /

  {cds-hooks-version}

  /cds-services.
  Including the hook version in the CDS-service description and the CDS-Hooks version in the call seams the less intrusive approach.
