## 11.1.3 Old classes

These classes, present in earlier versions of the `cgi` module, are still supported for backward compatibility. New applications should use the FieldStorage class.

`SvFormContentDict` single value form content as dictionary; assumes each field name occurs in the form only once.

`FormContentDict` multiple value form content as dictionary (the form items are lists of values). Useful if your form contains multiple fields with the same name.

Other classes (`FormContent`, `InterpFormContentDict`) are present for backwards compatibility with really old applications only. If you still use these and would be inconvenienced when they disappeared from a next version of this module, drop me a note.
