MP3ReloadRequest not exist

Hello,

sorry if you was speaking about this, but I found nothing in archives.

I use mod_mp3 0.40.

I add MP3ReloadRequest On" on my httpd.conf in the"mpd_mp3" VHost 
configuration and when I run apache I've :

# apachectl start
Syntax error on line 20 of /etc/apache/mod_mp3.conf:
Invalid command 'MP3ReloadRequest', perhaps mis-spelled or defined by a 
module not included in the server configuration
/usr/sbin/apachectl start: httpd could not be started

When i remove the MP3ReloadRequest apache run.

I check the sources and I found that MP3ReloadRequest is defined in 
directives.h but never usedn, even in the mp3_module_cmds.

It's normal or not ? because docs speaking about this, and I need this.

If it's removed, since which version ?

Thank you.
