presentation in ConTeXt and XeTeX

presentation in ConTeXt and XeTeX

[정 달영]

Dear all,

I tested presentation mode with "pre-green" module and it worked fine.
I also tested the same file with the addition of few lines which set  
my  personal font script for XeTeX-ConTeXt.

\usetypescriptfile[type-xkor]
\usetypescript[myface]
\switchtobodyfont[Myface, 12pt, rm]

Save the file(utf-8) and compiled it and I got errors:

Is there a way to use presentation module in ConTeXt-XeTeX  
environment using my fonts?

Thank you.
