[NTG-context] Alternative for selector in LMTX for different heading and reference texts for descriptions

[Christoph Reller]

Hi,

In ConTeXt MKIV, there are selectors (\defineselector, \select). In ConTeXt
LMTX, they are gone.

In LMTX, how can I achieve the following without using selectors:
(Different heading and reference texts for descriptions)

\defineselector[sel][max=2, n=2]
\definedescription[desc][headcommand={\setupselector[sel][n=1]}]
\starttext
\startdesc[title={\select{sel}{Long title}{Short}}, reference=desc]
  \input jojomayer
\stopdesc
\about[desc]
\stoptext

Any help is welcome!
Cheers,
Christoph
