On https://bids-specification.readthedocs.io/en/stable/03-modality-agnostic-files.html#dataset_descriptionjson in the License description there is a link to https://bids-specification.readthedocs.io/99-appendices/02-licenses.html which is broken.

A link that does work is https://bids-specification.readthedocs.io/en/stable/99-appendices/02-licenses.html, but I am not sure how that is supposed to work with the different versions.
