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

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
