Handle multiple locales in relationship population

Editor assessment

The subject states the fix directly: relationship population now handles multiple locales. It is imperative, free of junk, and understandable without project context beyond standard vocabulary. The fix type matches a localization correction, and the absent scope is acceptable because the operation is named. No body appears; describing how multi-locale documents previously populated with the wrong language would deepen the lesson, but a targeted fix like this can stand alone, and the parenthesized PR reference is conventional. Style is clean throughout. A solid, publishable example with modest depth.
