Nuprl Lemma : msg-body-cmp_wf

∀[f:Name ⟶ Type]. ∀[hdrs:Name List]. ∀[mcmp:hdr:Name ⟶ comparison(f hdr)].
  ∀a:{x:Message(f)| (msg-header(x) ∈ hdrs)} 
    (msg-body-cmp(mcmp) ∈ comparison({b:{m:Message(f)| (msg-header(m) ∈ hdrs)} | 
                                      (list-index-cmp(NameDeq;hdrs;λm.msg-header(m)) a b) = 0 ∈ ℤ} ))
