We are using AEM 6.4.8/6.5.8 and using experience fragments component in our page templates for header and footer implementations similar to WKND sites.
In template, we add experience fragment component with "/content/experience-fragments/us/header" as fragment path and when we create pages in /content/<project>/us/page, we are able to see the US Header.
Now we created language copy of the experience fragment to "/content/experience-fragments/fr/header", and now created page under "/content/<project>/fr/page", due to Localization implementations in experience fragment core component, automatically FR header is picked up on the FR page.
Now US Team, changed something in US header and planned to publish sometime next week.
parallelly FR team changed some page content and when trying to publish FR page, it is showing US Header as outdated as part of References publish.. which is weird.
the localization implementations done in core component experience-fragments model (com.adobe.cq.wcm.core.components.internal.models.v1.ExperienceFragmentImpl" also to be done for "com.adobe.cq.xf.impl.ExperienceFragmentsReferenceProvider" so check only for localized references.
