I probably wasn't clear enough. Here's my case:
BasePage.renderHead() adds veil.js as javascript resource reference. All my pages inherit from BasePage. But veil.js is only useful when a page has wicket ajax. If I declare that veil.js has a dependency on jquery then the result is that all pages get both veil.js and jquery. What I want is that pages that don't have ajax (i.e. no Wicket-Ajax or Wicket-Event libraries) don't include veil.js. I could do it on a per component basis but this would be cumbersome and error prone. So instead I used Martin's solution and conditionally render veil.js only if the headerResponse renders Wicket-Event.
