"__before_publishing_traverse__" is looking for nothing
and cannot return an object.
But it can modify the request and thereby change what
is looked for in the future.

"__bobo_traverse__" is looking for "name" and
it must return an object.

It, too, can modify the request and change what is looked
for in the future.
However, this is a bit dangerous, as "__bobo_traverse__"
(unlike __before_publishing_traverse__") is also
used by "Traversable.[un]restrictedTraverse" and
"Products.PageTemplateFile.Expressions.restrictedTraverse".
