On master, doc/src/sgml/biblio.sgml has a biblioentry for a pdf from ISO:
"Information technology — Database languages — SQL Technical Reports —
Part SQL Notation support 6: (JSON) for JavaScript Object"
That pdf was a 2017 edition but the url now points to .zip that no
longer exists.
The replacement is a ~200 euro pdf (2021). I'd be thankful if someone
would send the pdf to me; maybe I can update my JSON tests.
And we should remove that entry from the bibliography (or have it point
to the new page [1]).
