I believe this would be a helpful comment to discourage the practise of
adding generic emergency numbers, because it really happened.

These 2 points could go into a country (or region)-specific paragraph. The
Italian example was added because of foreign mappers converting the local
numbers incorrectly (and to help editor authors for creating verification
rules). People assuming the zero must go away is an issue, I even
experienced with my former (foreign) hosting provider that the Italian
numbers I added for whois (in the international format) were converted and
the zeros removed (and I had to exchange more than one email with their
support to get it rectified).

also country specific section
