Jen, that code is a hack. It could be useful, if it's submitted to the sourceforge.net site as a patch it will be considered for inclusion in the core... but it doesn't belong in the XOOPS Basic Manual.
My suggestion would be to have a section of useful hacks in the wiki at dev.xoops.org, if the XOOPS Core Hacks section of the forums isn't enough...
This is not good... I was using what I thought was the latest version from CVS for the docs site, but I see now that it's the older version you were talking about Monty.
Is there another way for me to get the latest version? Can someone from the team maybe contact me about this please? Or let me know who I should contact...
