Quickform: how to check two fields in one function using registerRule()

I have a form where I need to validate the user is not
repeating values already in a database table that has
two primary keys. Thus I need two fields from the
form to check but I only see this in examples:

function f ($element_name,$element_value){

}

Using quickform, how can I check two form fields in
ONE function?

Please only send one copy of your messages to the list.

It looks like rules in general are assumed to relate to one field but
rules such as the built-in Compare take 2 fields. Try checking that
one.
