This is as specified by HTML:

   Unchecked check boxes and not selected options are not 
   sent by the browser.

Zope allows you to use suffixes to tell its ZPublisher component
to hande form variables in a special way.

One of these suffixes is ":default". It is used in
an '<input type=hidden name="variable:default" value="some_value">'
to provide a default value for "variable".

You find a discription of more of these magic suffixes in
