I'd looked at them already,

Those catalogues aren't XML description of UI.
Let's take xfce4-terminal as a reference, the generated:

    /usr/share/xfce4/terminal/terminal-preferences.ui

doesn't use those functions, and it doesn't refer to glade at all.

The keyword is `create an UI using glade`, which xfce doesn't.
the xfce plugin is merely written to support designer using glade
to design XFCE widget.

And, XFCE doesn't need glade to create widget at runtime.

The real dependency of XFCE to use the glade-generated-xml is
GtkBuilder modules from GTK itself. From https://glade.gnome.org

I think you might confuse between libgladeui and libglade,
the former is the one shipped with glade,
the latter is a former dependency of gtk to use those glade generated
XML-base UI, and it's replaced by GtkBuilder from GTK itself.
