i18n-distinction for Search-Robots?

Hi,

how does ZMS provide a possibility for search robots to distinguish
between German and English pages?

I remember for former ZMS templates, there was always the
"index_ger.html / index_eng.html" within the url. But with
menu-navigation in myZMStheme60 it is gone.

And it would not so easy to implement this again, because there is still
a bug with catenated recursive embedded links (links, which embed an
embedded link, I posted this some time ago). There comes an site error,
when calling such pages with an ending index_xyz.html.

We are adding i18n to our site in the moment. Our temporarily
implementation for switching between eng and ger is done by a cookie and
modifying REQUEST.lang at the right positions within our template. It
works fine, but we have not solved how search engines can switch between
and identify eng and ger pages yet.
