What is the use of the $replacement property in the RegexIterator class.

Hi. I'm in the process of getting the PHPDoc classes showing the correct inherited properties and methods (public/protected but not private). I picked RecursiveRegexIterator (it has the largest number of xi:includes in the documentation) as a test. Using php --rc I see that the inheritance chain is RecursiveRegexIterator, RegexIterator, FilterIterator and IteratorIterator. The property $replacement is part of RegexIterator. I can see no documentation for this in phpdoc, nor in the Doxygen at http://www.php.net/~helly/php/ext/spl/ In all the examples I've made so far, var_dump()-ing the RegexIterator results in a ["replacement"]=>NULL Assigning a value to $replacement seems to have no bearing on the output.
