Also, if only the documentation or other non-code resources are under
this license, it's likely irrelevant for the purposes of conflict
checking. A dependent port is unlikely to be generating its
documentation by taking extracts from a dependency's docs and adding to
them.

We don't have a good way of indicating this kind of thing currently.
Often the license for the docs is just left out (not ideal because it
gives the user an incomplete picture of what licenses apply to the
installed files), or specified as though there was a choice of licenses,
e.g. {GPL-3+ CC-BY-SA-4} (which is not really true and could lead to
incorrect conflict checking in some cases). The other choice is to
verify manually that there is no conflict (which is what binary distros
do) and use license_noconflict, as cal mentioned.
