+The \pkg{xr} package can be used to reference labels in external
+document, e.g., when a work is split over different documents that
+need to be processed separateley, but has \cs{ref} or \cs{pageref}
+links between each other. With this update \cs{cite} commands and

+\pkg{xcite} by Enrico Gregorio.
+Note that for technical reasons \pkg{xr} doesn't work with
+\pkg{hyperref}. Use \pkg{xr-hyper} instead if you need the latter
