+        <!--
+        App dependency (not expressible in app-info.xsd): OpenRegister — every
+        Software Catalog entity is an OpenRegister object, and src/manifest.json
+        lists "openregister" as a required dependency.
+
+        min-version is therefore 32, NOT 28: openregister declares min-version="32"
+        because its lib/ContextChat/ContentProvider.php implements
+        OCP\ContextChat\IContentProvider, an interface core does not have before
+        Nextcloud 32. On NC 28-31 openregister refuses to install ("cannot be
+        installed because it is not compatible with this version of the server"), so
+        the app cannot function there. Declaring 28 advertised a range this app
+        cannot deliver. Same defect as openconnector#1173.
+
+        CI already tests stable32 only, so this changes the advertised app-store
+        range and nothing about what runs.
