What does fo: stand for?

I know this may seem a ridiculous question, but I'm trying to do some
documentation on FOs, and I don't see anything in the spec regarding whether
the fo: in the namespace prefix is supposed to refer to formatting object or
flow object. Is there a definitive answer to this somewhere in the spec that
someone knows of and I'm just missing it? 

thanks.
