[Twisted-web] fragments with child lookup

I would like to use the child lookup mechanism (locateChild or
childFactory) but then again, I want Fragments. I'm sure there is a
proper way to do what I want. Let my try to explain with a URL mapping
to templates mapping:
/ -> common.xml
/foo -> common.xml / foo.xml
/bar -> common.xml / bar.xml
/bar/baz -> common.xml / bar.xml / baz.xml
common.xml as well as bar.xml both have a 'sub-content' renderer, which
calls the next template. Of course this all happens dynamically.
I've tried two things:
a) make locateChild always return self, () and save which child it
contains (and which it has to return as it's 'sub-content'.
Unfortunately that stops the children lookup and I would have to invoke
it locateChild of the child with segments[1:] myself. That seems ugly.
b) make locateChild return the real Child. That seems the right thing to
do. But then I only get the latest child's template (i.e. baz.xml when
calling the URL '/bar/baz' in the example above). How do I make that
latest child render it's parents first?
