[xwiki-devs] [Idea] Post-loaded JSX

Hello all, I think it would be nice to have the possibility to post-load some of the JavaScript extensions, as a way to ease performance best practices for developers. (See http://developer.yahoo.com/performance/rules.html#postload for example). It would also allow people to easily add hungry third party scripts (like the google analytics tracker) in a non intrusive manner and not sacrificing performance (no need to modify/override htmlfooter.vm for example, a simple SX always-use will do). I see different ways of doing that : 1) Either we say all document JSX are post-loaded, and we move the hook down the DOM just before the closing </body> tag. 2) Either we have 2 hooks and we leave it as an option to be post-loaded. My preference goes to 1), as I don't see any good use case where a extension would need not to be post-loaded; and 2) is not so elegant to implement with the current SX mecanism. WDYT ? (Note: I'm not talking about file-system extensions here (JSFX), though the question could be asked for them as well - I need to give it more thoughts) Jerome.
