Nuprl Lemma : member-local-simulation-inputs
∀f:Name ─→ Type
∀[Info:Type]
∀es:EO+(Message(f)). ∀hdr:Name. ∀locs:bag(Id).
∀e:E. ∀v:Id × Info.
((v ∈ local-simulation-inputs(es;e;hdr;locs))
⇐⇒ ∃e':E
(e' ≤loc e
∧ (msg-header(info(e')) = hdr ∈ Name)
∧ fst(v) ↓∈ locs
∧ (v = msg-body(info(e')) ∈ (Id × Info))))
supposing hdr encodes Id × Info
