[NTG-context] No small caps?

I have Palatino as main font set up with \usetypescript[adobekb][8r] \loadmapfile[context-base] \usetypescript[palatino][8r] \setupbodyfont[palatino,rm,12pt] \switchtobodyfont[12pt] Plus I have \setupcapitals[sc=yes] \definestartstop[abstract] [before={\sc Abstract.\hskip1em}] But \starttext \startabstract In this article we will analyze a few techniques that can be used to approximate, by means of Bézier cubics, envelopes of circles centered on Bézier cubics. Such an approximation is useful, if not necessary, in several applications in many branches of computer graphics, ranging from CAD to outline font conversions. \stopabstract \stoptext does not give me Abstract in small caps. -- Giuseppe "Oblomov" Bilotta
