/**
 * A data holder built for the {@link AbstractResourceAggregatingHeaderResponse} that groups the
 * resource reference with a boolean representing whether it is css (or, if not, it is js), and the
 * string that was passed in to the responsible render*Reference method (for JS, this is ID, for
 * CSS, this is media).
 * 
 * It acts as a temporary data holder while the IHeaderContributors are being called so that at the
 * end of their traversal, we can render these references in an aggregated way, and still have the
 * appropriate data (i.e. was it CSS or JS) to render it properly.
