PHP 4 to PHP 5 change - allowing assignment to pass by reference function parameters.

Hi. Is there any documentation regarding this change? function ca_getUserDetails($pUserid, &$pResults=array()) {} is fully allowable in PHP 5+, but not in PHP 4. Depending upon version, the error is ... Parse error: parse error, expecting ')' or Parse error: syntax error, unexpected '=', expecting ')' I'm just looking for some notes to pass on. Thank you.
