Hi,
according to the section "Custom citation renderings" in the bibliography manual, I have specified an own setup for citation rendering.
However, this seems only to work for single citations (of one source). I want to also specify the separator but did not get it to run.
Here is a minimal example:
```
\setupinteraction[state=start]
\startbuffer[testdata]
@Book{knuth1,
author = {Donald E. Knuth},
title = {TEX and METAFONT. New directions in typesetting},
year = {1979},
publisher = {Addison-Wesley},
}
@Article{someother,
author = {Some Person and Some Otherperson},
title = {Another title},
year = {1900},
}
\stopbuffer
% enable tracing
\enabletrackers[publications, publications.crossref, publications.details, publications.cite, publications.strings]
\usebtxdataset[main][testdata.buffer]
\usebtxdefinitions[aps]
\setupbtx[dataset=main]
\definebtxrendering[bibrendering][aps][dataset=main, numbering=short]
\setupbtxlist[aps][
alternative=b,
distance=.5em,
]
\definebtx[aps:cite:special][aps:cite][
left={((},
right={))},
separator:2={sfd},
separator:3={sfd},
separator:4={sfd},
]
\startsetups btx:aps:cite:special
% just a dummy
\btxcitereference
\currentbtxtag
\stopsetups
\setupbtx[aps:cite][
alternative=special,
]
\starttext
Both said something~\cite[knuth1, someother].
\placelistofpublications[bibrendering]
\stoptext
```
The output of this is:
> Both said something ((knuth1someother)).
How can I get the separator to work? My expectation would be:
> Both said something ((knuth1sfdsomeother)).
or
> Both said something ((knuth1sfd someother)).
Best,
Gerion
