[NTG-context] bibl-apa.tex wrong?

Hello, This (http://www.liu.edu/cwis/cwp/library/workshop/citapa.htm) and just about any other site I look at specifies publisher info as ": <publisher name>", whereas bibl-apa.tex specifies it as "<publisher name>, ". Why is the file called bibl-apa.tex if it doesn't follow APA rules? Am I missing something thanks, Matej
