Mmmh... Let's consider a very practical case (sorry for cocoon-dev flooding on avalon-dev ;) : in a Cocoon sitemap, we have e.g. a <map:generate type="file">. How can we check at sitemap load time if there actually exists a "file" specialization for the Generator role and that this statement is valid ? De we have to resort to a lookup()/release() and see if no exception occurs ?
