[NTG-context] ConTeXt+ispell--> output with uncorrect words in overline red.

Hi, I'm amazing if it's possible to process, by some way, a text written in context for context overline in red the incorrect words (via ispell). Overline in red is any example. For example, we could \frame this words. How it could be done?, if it's. Xan. PS: Please, CCme.
