hasattr(self.aq_base, 'index_html') should probably work.
aq_base returns the unwrapped base object.
There is other aq_wrapper methods as well:
aq_parent (returns the parent wrapper) and aq_self.
I don't really know (of the top of my brain) the differens
between aq_base and aq_self.
There is however a wiki some where in the Interface section
on Zope.org that tells you more, no link pops in to my mind
at the moment so you just have to search for it.
I think hasattr() is a better way to look upp attributes but
that's just my 5 cents.
