This is default: xmlns:wicket="http://wicket.sourceforge.net This will change Wickets namespace: xmlns:sherpa="http://wicket.sourceforge.net But note that all tags must be changed now, not just the wicket:id attribute. And I'm fairly sure you'll stumble across some loose ends here. Many part of Wickets core are testing for the namespace, but not all.

Dear Juergen, Thanks for your answer and paying attention to my request! I have tested those changes on my toy application and they seem to have no other side effects... By the way do you know if it is possible to "force" wicket to use something different as the wicket:id for recognizing HTML/XML tags as wicket components? Not that we have anything against the wicket:id attribute but now that we are able to mock JSP-like tags (mainly because our clients are more used them) it would be nice to have a sherpa:id attribute as well: just to make more clear when are working with our own components.
