Auth_OpenID_AuthRequest::addExtensionArg PHP Method

Use caution when adding arguments, because they will be URL-escaped and appended to the redirect URL, which can easily get quite long.

public addExtensionArg ( string $namespace, string $key, string $value )
$namespace	string	The namespace for the extension. For example, the simple registration extension uses the namespace 'sreg'.
$key	string	The key within the extension namespace. For example, the nickname field in the simple registration extension's key is 'nickname'.
$value	string	The value to provide to the server for this argument.

    function addExtensionArg($namespace, $key, $value)
    {
        return $this->message->setArg($namespace, $key, $value);
    }
