We would need to add a support for a new wms_metadataurl metadata in the 
WMS GetCapabilities code.  This is not really a change to the mapfile 
format since it's a metadata entry and the mapfile parser doesn't do any 
validation on metadata.

Then to have access to this information in chameleon the WMS 
capabilities parser code in Chameleon would have to be enhanced to 
handle this new piece of information.  There could be more or less work 
involved in Chameleon depending on what you want to do with this URL.

There's already a bug about adding this to the WMS capabilities in 
MapServer, you could add yourself in the CC of the bug to be informed 
when we get to it:
