The mom manual doesn't mention %X refer field: http://www.schaffter.ca/mom/momdoc/refer.html#fields-quick
Does it mean mom will not understand, or ignore %X field? I use for DOI information, e.g. %X DOI: 10.1016/j.actamat.2010.03.013 Should I use %O for it if I want to use mom? Thank you Anton P.S. I like this groff thing more and more!
