It's not hard to work around Firefox's lack of support for <maction  
actiontype="tooltip">, with a touch of javascript. See, e.g.

      http://golem.ph.utexas.edu/~distler/blog/archives/002105.html#WebkitU1

as an example. I don't think minting a redundant @title attribute  
would be a good idea.
