find out if page is public

Hi,

I am looking for a function which tells me if a page is public or
restricted.

attr_dc_accessrights_restricted is not what I am looking for, because it
considers only the page where it is set and not the sub-pages.

hasAccess does not do the job either, because it just tells if the
authenticated user has access.

I need a more general function which is independent of the logged in
user. I.e. to put a "This is a public place" - sign on each public page
or to tell a cache to store a public page (with no authenticated users -
elements) thought somebody is logged in.

Regards
PeterZ
