[Zope] editing language property on root folder ?

[chas]

Seems that we can't add a property named 'language' to the
root folder - I guess zope uses that internally. It's OK to
place it on any other folder.

This is a bit of a shame b/c I would have like to just make
language='cn' on the root folder and be done with it. 
Why not have the language property editable on the root folder
just like the title is ?  

Would maybe help those of us doing multilingual sites.

Or am I being dense again ?
