Do embargoed Dandisets need a license?

[kabilar]

I have an embargoed Dandiset (https://dandiarchive.org/dandiset/001288/draft) which is throwing a metadata validation error.

Are we required to have a license for embargoed Dandisets? Perhaps adding a license should be part of the unembargo workflow, and the metadata validation error should not be displayed for an embargoed Dandiset.

Thanks.
