{ [a:Id]. [d1,d2:SecurityData].  uiff(data(a) = <d1, d2>;False) }

{ Proof }



Definitions occuring in Statement :  sdata-pair: <d1, d2> id-sdata: data(x) sdata: SecurityData Id: Id uiff: uiff(P;Q) uall: [x:A]. B[x] false: False equal: s = t
Definitions :  uall: [x:A]. B[x] uiff: uiff(P;Q) false: False member: t  T and: P  Q uimplies: b supposing a prop: sdata: SecurityData id-sdata: data(x) sdata-pair: <d1, d2> tree_leaf: tree_leaf(x) node: tree_node(<x, y>) tree_node: tree_node(x) tree: Tree(E) tree_con: tree_con(E;T)
Lemmas :  sdata_wf id-sdata_wf sdata-pair_wf false_wf Id_wf tree_wf

\mforall{}[a:Id].  \mforall{}[d1,d2:SecurityData].    uiff(data(a)  =  <d1,  d2>False)
