The newest version!
Declaration of Persistent Identifier Data Exchange Format (pidef) root element with two
sub-elements: "header" and "data".
- header is a mandatory field and must occur only once
- data element contains the actual information. It exists also only once if the request
could be successfully processed.
In case of error the fields in header: status_code and message shall return an unique error id
and a human readable text explaining the cause, which can be repeated in every human
language supported by the software.
