That is RSS, it bases on XML, but it have ONLY fields like title,channel,item,rss etc. So creating it is NONSENS.
Or you could use RSS for new maps/textures/builds/players.
Wrong, its only for news. For other things with tree of items with values is XML (and RSS bases on it). And without tree, just section and field is INI. But RSS cannot be used like this, because it's impossible to create it with RSS specification, and if it's not OK with RSS specification, then its XML. So:
RSS CANNOT BE USED AS INFORMATION HOLDER (even if you want to lose ur time to do that, this is still nonsens).
