This + is a suffix and not a freestanding character, right? So "GPL-2.0+" is valid but "GPL-2.0 +" would not be valid? In this case there would be no issue to have a plus as part of a licenseref: there is no possible ambiguity. Then again we would be better off to get rid of the plus entirely! -- Cordially Philippe Ombredanne _______________________________________________ Spdx-tech mailing list Spdx-tech@lists.spdx.org https://lists.spdx.org/mailman/listinfo/spdx-tech
