as with a lot of things in TAL, the answer is that there is no
built-in TAL gunk for that so you use python:
    
      <a class="navigation" target="main" 
               tal:attributes="href url" 
               tal:content="python: r.object.title_or_id().lower()">ID</a>


explanation: path expressions like "r/object/title_or_id"
are equivalent to python object containment like
r.object.title_or_id. but path expressions will automagically
call the last item on the path if it's callable, and you have
to explicitly do that in python with (). Next, the result of
title_or_id is a string, and python strings have lots of useful
methods.  some_string.lower() returns a lowercased copy of the input
string.
