In general, this is impossible (because "page_header" does not know
which object called it (unless the "security context stack" is analysed)).

In the special case, when "index_html" is called directly through the
Web (via "ZPublisher"), "index_html" is available as "REQUEST.PUBLISHED".

However, a better idea is probably to set a "parent_title" variable
in the calling context and use it in the called DTML method, when it is
defined.
