+# Strip the PRI split configuration from a MakePri-generated priconfig.xml.
+#
+# `MakePri.exe createconfig` emits a <packaging> section telling `MakePri.exe new` to
+# split resource candidates into separate resource packages (resources.language-*.pri,
+# resources.scale-*.pri, ...), leaving the main resources.pri with default-context
+# candidates only. A monolithic MSIX package loads nothing but the resources.pri at its
+# package root, so any split dimension - autoResourcePackage qualifiers (Language, Scale,
+# DXFeatureLevel, ...) as well as manual resourcePackage entries - would strip its
+# candidates from the shipped package, e.g. every non-default UI language would silently
+# fall back to the source language.
+#
+# This script therefore removes the whole <packaging> element. The schema declares it
+# optional, and leaving an empty one behind would make MakePri warn about a missing
+# packaging mode. The file is rewritten in place as UTF-8 without BOM.
+#
+# Usage (the Windows CI calls it between `MakePri.exe createconfig` and `MakePri.exe new`):
+#   pwsh -NoProfile -ExecutionPolicy Bypass -File strip-priconfig-packaging-node.ps1 -Path priconfig.xml -Verbose
