In free text format, mentioning "see above" is OK.  The structured
format should allow mentioning large parts only once.

It is not OK to mention in debian/copyright that the software "can be
bound" by a license "expressed elsewhere".

In free text format it is, in my opinion, OK to mention "the files in
the directories ... are copyrighted by a combination of some of the
following copyright holders: ... and are licensed under the terms
of ...".
