crossmark_domain_exclusive

This tag tells the system whether you only ever expect to see your content on a limited set of web domains (i.e. your own website) or whether it can legitimately reside elsewhere. For most OA publishers the value here will always be false. eLife publishes under CC-BY and CC0 so this should be false
resource content_version

This is separate to CrossMark, unless you particularly want it to display in the record tab, in which case you should include it in your CrossMark deposit. It’s not needed to make CrossMark work.
It would be too difficult to add the urls for each of the different versions of an article in an automated fashion, so deleting this from the sample as it is not required
