Someone posted a bug that sounds like your JS code in the Zotero
forum. It’s related to author substitution on the MLA style. This
reminds me, on this:
<author> <substitute> <choose> <editor/> <titles/> </choose> </substitute> </author>
Did we agree to remove the “choose” wrapper?
Also, I noticed you have the short form of number “no”? What about
"n", which is far more common?
