Nuprl Lemma : has-header-and-in-locs_wf
∀[f:Name ⟶ Type]. ∀[msg:Message(f)]. ∀[hdr:Name]. ∀[locs:bag(Id)].
has-header-and-in-locs(msg;hdr;locs) ∈ 𝔹 supposing hdr encodes Id × Top
Proof
Definitions occuring in Statement :
has-header-and-in-locs: has-header-and-in-locs(msg;hdr;locs),
encodes-msg-type: hdr encodes T,
Message: Message(f),
Id: Id,
name: Name,
bool: 𝔹,
uimplies: b supposing a,
uall: ∀[x:A]. B[x],
top: Top,
member: t ∈ T,
function: x:A ⟶ B[x],
product: x:A × B[x],
universe: Type,
bag: bag(T)
Definitions unfolded in proof :
uall: ∀[x:A]. B[x],
member: t ∈ T,
uimplies: b supposing a,
has-header-and-in-locs: has-header-and-in-locs(msg;hdr;locs),
all: ∀x:A. B[x],
implies: P ⇒ Q,
bool: 𝔹,
unit: Unit,
it: ⋅,
btrue: tt,
band: p ∧b q,
ifthenelse: if b then t else f fi ,
uiff: uiff(P;Q),
and: P ∧ Q,
subtype_rel: A ⊆r B,
