survey persist - temporarily save data

Hi,

a question about
<SURVEY PERSIST="yes" ...

In the syntax reference guide,
http://modsurvey.org/text/mod_survey_syntax_reference.pdf, you can read on
page 6

"PERSIST (...) Whether to allow respondent to temporarily save answer in
order to return later for finishing the survey."

But in the "for beginners" handbook,
http://modsurvey.org/text/mod_survey_for_beginners.pdf, on page 12 is
written

"Persistance: Data persistence has been supported in earlier versions of
Mod_Survey but has not yet been ported to the latest version. Data
persistence is the respondent option of saving data temporarily in order
to return later to finish the survey."

What is correct and can I use PERSIST in the current stable version?

Alternative: Where can I change the expire time of the cookie? So I can do
the same without PERSIT by setting this value to 20 days or something like
that.

Clemens
