Hello Bart,
Try
\starttypescript[serif][caslon][uc]
\definefontsynonym[CaslonRegular][name:CaslonOldFaceBT-Roman][encoding=uc]
\definefontsynonym[CaslonItalic][name:CaslonOldFaceBT-Italic][encoding=uc]
\definefontsynonym[CaslonBold][name:CaslonOldFaceBT-Heavy][encoding=uc]
\stoptypescript
\starttypescript[serif][caslon][name]
\definefontsynonym [Serif] [CaslonRegular]
\definefontsynonym [SerifItalic] [CaslonItalic]
\definefontsynonym [SerifBold] [CaslonBold]
\stoptypescript
\starttypescript[caslon][uc]
\definetypeface[caslon][rm][serif][caslon][default][encoding=uc]
\stoptypescript
\usetypescript[caslon][uc]
\setupbodyfont[caslon, 12pt]
\starttext
Testing {\bf Testing} {\it Testing}
\stoptext
Note the two changes: \definetypeface's in the first typescript have
been replaced with \definefontsynonym commands, and the font names have
been prepended with "name:", forcing XeTeX to look for an installed font
instead of a TFM (in plain XeTeX, you get the same result by surrounding
the font name with double quotes).
I am unable to test the typescript because I don't have Caslon Old
Face, but it works when I replace the font names with the appropriate
faces from Adobe Caslon, which I have.
Arthur
