> Cuurently org.apache.wicket.Page#getPageParameters() and org.apache.wicket.request.resource.IResource.Attributes#getParameters() return a mutable PageParameters. For the latter this is not a problem since it is not stored and reused for url generation.
> In the case with Page#getPageParameters() this instance is live until the page instance is alive. Some users make a mistake to modify the parameters (by using #add, #set, #remove) just to create an Url for some other page and later page's pageparameters are no more the real ones.
> We can improve that by introducing an interface with getter methods only.
