     # Normally, permissions to read or write every attribute in a type are
     # granted if the user has the global permission to read or

     # to be protected by specific permissions, set one or the 2 next boolean
     # values to "True". In this case, you will create a new "field-only"
     # read and/or write permission. If you need to protect several fields
     # with the same read/write permission, you can avoid defining one
     # specific permission for every field by specifying a "named"
     # permission (string) instead of assigning "True" to the following
     # arg(s). A named permission will be global to your whole Zope site, so
     # take care to the naming convention. Typically, a named permission is
     # of the form: "<yourAppName>: Write|Read ---". If, for example, I want
     # to define, for my application "MedicalFolder" a specific permission
     # for a bunch of fields that can only be modified by a doctor, I can
