I'm not sure it works, if I understand well, the following EL:

${config.a.b.c}

translates into (through reflexion):

config.get("a").get("b").get("c");

but what is supposed to return the get("b") part ? the value of "a.b" 
that's "z" or the subset under "a.b" containing the "c", "c.d.e" and 
"c.d.e.f" elements ?
