LDC-E5404 — Revision edge points at no declared edition

What it means

A revision edge links two declared editions: the previous one its operations start from and the next one they must produce. Both names must resolve to editions declared in the same package. When either side names something undeclared, there is nothing to apply the operations to, so the compiler reports the broken link before looking at any operation.

Example

Arxo Law

language "law.core" version "0.2";
package demo.diagnostics version "0.1.0";
namespace "urn:law:demo:diagnostics";

source ORDER { kind ministerial_order; }
edition ED_2025 of ORDER { language ru; officiality official; }
edition ED_2026 of ORDER { language ru; officiality official; }
fragment F_OLD in ED_2025 { kind article; locator "article/5";
  text ru official """старая редакция"""; }
fragment F_NEW in ED_2026 { kind article; locator "article/5";
  text ru official """новая редакция"""; }
revision LAW_1 {
  previous ED_1999;
  next ED_2026;
  relation amends;
  op replace { locator "article/5"; language ru; text """новая редакция"""; }
}

Fix

Arxo Law

language "law.core" version "0.2";
package demo.diagnostics version "0.1.0";
namespace "urn:law:demo:diagnostics";

source ORDER { kind ministerial_order; }
edition ED_2025 of ORDER { language ru; officiality official; }
edition ED_2026 of ORDER { language ru; officiality official; }
fragment F_OLD in ED_2025 { kind article; locator "article/5";
  text ru official """старая редакция"""; }
fragment F_NEW in ED_2026 { kind article; locator "article/5";
  text ru official """новая редакция"""; }
revision LAW_1 {
  previous ED_2025;
  next ED_2026;
  relation amends;
  op replace { locator "article/5"; language ru; text """новая редакция"""; }
}
