[NTG-context] alternative \about for \section?

Dear list, I have the following sample: \starttext \startsection[title={Section}, label={different section label}, reference={key:section}] \about[key:section] \stopsection \stoptext I thought that label would give me an alternative section title in references. Is there any way to get it? BTW, what is the purpose of label? Many thanks for your help, Pablo -- http://www.ousia.tk
