G.9:5 — Interfaces (minimal I/O; conceptual)
Preface node
heading:g-9-5-interfaces-minimal-i-o-conceptual:80933
What this page is
This is generated FPF reference text from the specification preface or supporting sections. It helps interpret FPF; it is not FPF Reference product documentation.
Methodology
Use it to understand how the specification wants to be read, then return to a route, pattern, or work packet for active work. Cite generated IDs only when the wording changes the task decision.
Content
Publication records are conceptual here; serialisations belong in shipping and interop publication forms (see G.10 and interop annexes), not in G.9.
