+# This abstraction is designed to be used in a child profile to limit what
+# confined application can invoke via xdg-open helper. xdg-open abstraction
+# will allow to use gio-open, kde-open5 and other helpers of the different
+# desktop environments.
+#
+# Usage example:
+#
+# ```
+# profile foo /usr/bin/foo {
+# ...
+# /usr/bin/xdg-open rPx -> foo//xdg-open,
+# ...
+# } # end of main profile
+#
+# # out-of-line child profile
+# profile foo//xdg-open {
+#   include <abstractions/xdg-open>
+#
+#   # Enable a11y support if considered required by
+#   # profile author for (rare) error message boxes.
+#   include <abstractions/dbus-accessibility>
+#
+#   # Enable gstreamer support if considered required by
+#   # profile author for (rare) error message boxes.
+#   include if exists <abstractions/gstreamer>
