Maybe you could explain what kind of 'dynamics' you have in XWiki?

Here are some use cases we have:

* We have an Extension Manager which allows us to install various kind of extensions (http://extensions.xwiki.org) at runtime in your wiki. One type of extensions is a JAR which contains Java classes and components. All components found in that JAR are discovered and registered in the Component Manager. For example there could be a Java Macro in the JAR and in the WYSIWYG editor we list all available macros so that new macro will appear automatically in the list. A component can also override an existing component, thus replacing it altogether.

* Another use case is that users can define new wiki macros in wiki pages (there's a form with various fields like macro id, macro description, macro parameters and macro content which is a script to execute. When the page is saved, an event is fired and we have a WikiMacro Manager component listening which then registers that wiki macro as a Macro Component against the Component Manager.

* A last use case is that in wiki pages we can put scripts (velocity, groovy, python, ruby to name a few) and we can define a Java Class in script and register through scripting against the Component Manager making the new component either replace an existing one or register it as a new component.

More information on our Component model is available here too in case it's useful: http://extensions.xwiki.org/xwiki/bin/view/Extension/Component+Module
 
Thanks Mark!
