Between the three bibliography-setting commands of Context mkiv, what is the hierarchy?
\usebtxdefinitions[aps]
\definebtxrendering[default][chicago][specification=chicago,sorttype=authoryear,numbering=no]
\setupbtxlist[chicago][]
If the only thing I need is chicago, and use \usebtxdefinitions[chicago], I get a blank bibliography with <article>
instead of the citation, although chicago is mentioned among the basic styles. So I use it as written and it works OK, but I just want to understand the logic.
