Indent Comma Format (ICF)

The canonical specification for the ICF language. This is the document referenced by @specification https://icformat.org/icf/specification/v1.1. Version 1.1.1 is a clarification patch of 1.1: it adds Scope (§80), Security Considerations (§81), Implementation Limits (§82) and Conformance (§83). Document validity and interpretation are unchanged — documents continue to declare @version 1.1 — and every 1.1 section number is preserved.
