Can a landing page be a page section or popup, for example where a DOI is registered for a chapter or a figure? Could a DOI potentially resolve to a URL such as https://test.example.org/a-larger-work#figure-1 or does the landing page have to be an individual file?
(To clarify, the full page – in the example, this would be https://test.example.org/a-larger-work – is also the landing page for its own, separate, DOI.)
