Can can return a string from "__getitem__" (without problem),
*but* you cannot use this string during URL traversal.

By the way, it does not matter for URL traversal whether the string (or
other simple type object or object without docstring) was
returned by "__getitem__", "getattr" or "__bobo_traverse__"
(these are the possibilities to obtain the subobject during URL
traversal) -- the publisher will in all cases reject it.
