Analog function question

I am just noticing (with disbelief) that analog functions
cannot take arrays as inputs (since I don't see any mention
of it in LRM v2.2).  Is this observation/conclusion correct?

analog function real maxValue;
input n1, n2 ;
real n1, n2 ;
begin
// code to compare potential of two signal
maxValue = (n1 > n2) ? n1 : n2 ;
end
endfunction

Is there a way to make "n1" and/or "n2" an array?

Thanks,

Arpad
