The et-al documentation refers to "the number of names in a name variable.”
<names variable="author editor”>, does that mean the total number of authors + editors, or authors and editors considered separately?
In other words, if
et-al-use-first is 3,
et-al-min is 4 and there are six authors and four editors, are three total names shown or six total names?
I assumed the former but I encountered a test that seems to require the latter.
