[NTG-context] Get section's uservarialbe inside the section

Dear List, I have sections tagged with authors: \startsection[title={Title}][author={Author}] ... \stopsection The authors were to be included in the table of contents using \structurelistuservariable{author}. Now I would also like to mention the authors inside the sections, but \startsection[title={Title}][author={Author}] \structurelistuservariable{author} \stopsection doesn't work. Could anyone help me with this? Thanks! Best, Sylvain
