hi,
sorry for the previous mail, I was reading my mail with horde and the
figures did not rendered the format correctly and now I'm seeing it in
Thunderbird and it represents them correctly now ;)
all is documented in the doc/README.developer
case 1) with a structure "value_string"
case 2) if you're using the svn version of wireshark, you're lucky, you
can use the new feature "range_string" else see the following
http://www.wireshark.org/lists/wireshark-dev/200612/msg00039.html
case 3) "true_false_string"
Hope that helps,
Sebastien Tandel
