Description:
------------
SoapFault may set properties on itself according to values passed in through the constructor. These values are not documented and not part of the class "definition", and when set are publicly accessible.

At the very least the documentation should be updated to reflect the six potential properties.

A step beyond that would be to consider adding getter methods, like Exception classes typically have. The properties could then be kept private, though that would be a bit of a BC break (even if it was undocumented).

(copied from http://php.net/manual/en/class.soapfault.php#97875)

<?php
try {
    throw new SoapFault('code', 'string', 'actor', 'detail', 'name', 'header');
} catch (Exception $ex) {
    var_dump($ex->faultcode, $ex->faultstring, $ex->faultactor, $ex->detail, $ex->_name, $ex->headerfault);
}
?>
