[NTG-context] Including xfig graphics

Hi there, I'm pretty new to ConTeXt and stumbled upon a problem when trying to use Xfig: I'm trying to create figures with xfig and including them in my ConTeXt document. I would export them as PDF, but unfortunately I have TeX math inside the figure and I'd like to have native fonts. I used to use a combinded LaTeX/PDF export in the past with LaTeX. Is there any practical solution to this? Regards, Florian.
