i start to get lost again.  i understand that i can reference avps of
the above looked up domain as $fd.attribute_name.  but why can't the
domain that is being looked up simply be taken from the kamailio pseudo
variable as it is written ($fd in the example) without assuming that it
is in $fu.fd?

or is it so that second argument of lookup_domain cannot be a k pseudo
variables at all?  for example, can i take if from r-uri host like this:

lookup_domain("$fd", "$rd");
