[Mediawiki-l] Per-namespace categories

[Kenneth Porter]

I'm using a site which covers multiple related games and there are topics 
that have the same name for each game. These topics are then gathered into 
hierarchies of MediaWiki categories. Is there any way to use some kind of 
namespace mechanism to allow the same category name to be used for multiple 
games? For example, given the game prefix names WoW and WCIII, could I have 
WoW:Categories and WCIII:Categories?
