XWiki requests schematic

Hi, I'm currently trying to understand how exactly are requests dispatched in XWiki. The document http://www.xwiki.org/xwiki/bin/view/DevGuide/Architecture was helpful to understand the general architecture, but I wanted something more request centric. So I've made a quick schematic with my current understanding of requests in xwiki: http://perso.enst.fr/~oliveira/ I would really appreciate your comments and corrections, Kind regards, Pablo
