Igor, Thanks for the solution! I'll go that route for now.
However, I'm not convinced that supporting alternate stylesheets is outside the scope of wicket core. Mozilla browsers support switching to alternate stylesheets from a menu option: http://www.w3.org/Style/Examples/007/alternatives.html That alone is probably not a good enough incentive to include it in core. But my use case is to improve accessibility. The site I'm making is for senior citizens, so I'm providing them with a way to easily scale the size of the font displayed on the site by clicking font size icons on the page. This technique is explained here: http://alistapart.com/stories/alternate/ This solution uses javascript to activate and deactivate the alternate stylesheets. I prefer to utilize javascript for quick stylesheet changes rather than a round-trip to the server. I realize I could accomplish the same thing with server round-trips and not need any custom HeaderContributor. Lastly, it is possible to group stylesheets together and activate or deactivate them all at once if they have the same title. Adding that attribute would make it more robust. Regardless, as you have shown, it isn't hard to implement my own IHeaderContributor. I just wasn't sure how to go about it, and now I am. So perhaps you are right in that it is best left out of core.
