Due to adopting new policy on references in Crossref metadata deposits
https://www.crossref.org/reference-distribution/?utm_term=on%20our%20website&utm_campaign=Update%20your%20setting%20for%20distribution%20of%20references%20under%20the%20new%20policy&utm_content=email&utm_source=Act-On+Software&utm_medium=email&cm_mmc=Act-On%20Software--email--Update%20your%20setting%20for%20distribution%20of%20references%20under%20the%20new%20policy-_-on%20our%20website
it could be good to add options in CrossRef export plugin to manage references according to CrossRef reference policy options.
Thanks
