[Taxacom] Problem with authors of taxa

Art. 50 was modified in the 4th ed. of the Code, hence an interpretation 
dating from a time when the 3rd ed. was in force is potentially problematic.


3rd. ed. (1985):
50(a) -- "If it is clear from the contents of the publication that only 
one of joint authors, or some other person, is alone responsible both 
for the name and for satisfying the criteria of availability other than 
publication, then that person is the author of the name."

4th ed. (1999):
50.1. -- "If a work is by more than one person but it is clear from the 
contents that only one of these is responsible for the name [...], then 
that person is the author [...]."
50.1.1. -- "However, if it is clear from the contents that some person 
other than an author of the work is alone responsible both for the name 
[...] and for satisfying the criteria of availability other than actual 
publication, then that other person is the author of the name [...]."


The current version treats cases where a name is declared authored by 
one of the authors of the work (e.g., Jones in Jones & Smith) 
differently than cases where the declared author is external (e.g., 
Jakes in Jones & Smith). In the first situation (50.1.), simple evidence 
that the declared author was responsible *for the name* is enough to 
restrict the authorship. (Citing the author's name after a new species 
name does the job.) In the second situation (50.1.1.), you need evidence 
that the external person was responsible for the name AND *for 
satisfying the criteria of availability other than actual publication* 
to make the external person the author. (Typically, this means evidence 
that both the name and the description that made it available were 
supplied by the external person.)

Back in 1994, the article that was in force did not make any such 
distinction; it required evidence that the declared author was 
"responsible both for the name and for satisfying the criteria of 
availability other than publication" in both situations.

Thus it appears that, for cases like "Ribeiro & Buckup in Ribeiro, 
Buckup, Gomes & Araujowas", Ng's interpretation was possible in 1994, 
but is not any more...
