Nuprl Lemma : outl-class_wf
∀[Info,A:Type]. ∀[X:EClass(A + Top)].  (outl-class(X) ∈ EClass(A))
Proof
Definitions occuring in Statement : 
outl-class: outl-class(X), 
eclass: EClass(A[eo; e]), 
uall: ∀[x:A]. B[x], 
top: Top, 
member: t ∈ T, 
union: left + right, 
universe: Type
Definitions unfolded in proof : 
uall: ∀[x:A]. B[x], 
member: t ∈ T, 
outl-class: outl-class(X), 
all: ∀x:A. B[x], 
subtype_rel: A ⊆r B, 
uimplies: b supposing a, 
top: Top, 
prop: ℙ, 
outl: outl(x), 
isl: isl(x), 
assert: ↑b, 
ifthenelse: if b then t else f fi , 
bfalse: ff, 
false: False, 
so_lambda: λ2x y.t[x; y], 
so_apply: x[s1;s2]
Latex:
\mforall{}[Info,A:Type].  \mforall{}[X:EClass(A  +  Top)].    (outl-class(X)  \mmember{}  EClass(A))
