Multiple refnames

Hi, according to docbook documentation it's possible to have multiple <refname> tags inside <refnamediv>. I need it to add names for procedural functions and equivalent oo-methods/properties. Make doesn't complain about it, but in output it looks little bit strange: see: http://georg.fooassociates.com/mysqli/ref.mysqli.html and http://georg.fooassociates.com/mysqli/function.mysqli-affected-rows.html Is there any change to fix it, or does somebody have a better idea how to implement both names inside <refnamediv> ?! Regards Georg
