Maybe I misunderstand, but if I do:
{

  \relative c' { c4 d e f << { g a g f } \\ { e2 d } >> e4 f e d c1 }
  {s1\mf s4\< s\! s\> s\! s1\p s }

}

The dynamics show up in the MIDI. And if they're separated into variables, I 
can change the dynamics and the music independantly and easily, without fuss or 
muss.

I extrapolated the idea from that, Using Variables to Save Typing. Or something 
like that.
