In the archive I found a report posted by Juergen:
<http://www.appelsiini.net/keitai-l/archives/2000-08/0354.html>. The
replies to this gave some details, which were that the emails included
an (obscured) link to the emergency telephone number. How to include
such a link in an email? Ren wrote that on certain handsets you can
cause an email to be interpreted as HTML by putting "</XPLAINTEXT>" at
the beginning. (This sort of implies that those handsets use the
browser software to show emails, and insert a magic tag at the
beginning that *almost* disables markup in the email.)
An alternative explanation was that a plain text email could contain
an (apparently harmless) http URL that links to a page that in turn
contains a link to a tel URL.
What happens if a page has an <img> tag that uses a tel URL? Does the
browser treat the image as broken, or does it behave as if the user
selected an <a> link to the URL?
I thought that newer handsets would always display the number given
in a tel link and prompt for confirmation before actually dialling.
Is this not correct?
