theorem ALL_SNa:
assumes a: "\<Gamma> \<turnstile> M \<turnstile> \<Delta>"
shows "SNa M"
proof -
fix x have "(idc \<Delta> x) ccloses \<Delta>" by (simp add: ccloses_id)
moreover
fix a have "(idn \<Gamma> a) ncloses \<Gamma>" by (simp add: ncloses_id)
ultimately have "SNa ((idn \<Gamma> a),(idc \<Delta> x)<M>)" using a by (simp add: all_CAND)
moreover
have "((idn \<Gamma> a),(idc \<Delta> x)<M>) \<longrightarrow>\<^sub>a* M" by (simp add: id_redu)
ultimately show "SNa M" by (simp add: a_star_preserves_SNa)
