[NTG-context] Referencing examples with identical labels in different sections

All, I have in my environment file: \defineenumeration [example] [location=serried, width=broad, text={\color[heavygreen]\bgroup\bold{Example}}, stopper={.\egroup}, style=slanted, inbetween=\blank, after=\blank] Now, I have a chapter with four sections. What can I do so that \startexample[exmpl:one] ... \stopexample in section one will be differentiated from \startexample[exmpl:one] ... \stopexample in section two? That is, a label in section two that refers to the exmpl:one will reference the exmpl:one in section one.
