In the DPUB specifications, the doc-biblioentry role is marked as deprecated.

It requires an accessible name from author (aria-label or aria-labelledby) but does not support/inherit any ARIA states or properties (no aria-label or aria-labelledby?).

Additionally, a note clarifies that, according to ARIA, it should not be used because it is expected to be an accessible child of a list, which is not allowed.

Would it be reasonable to remove it from the list of roles entirely?
