While understanding what it means, I guess this might imply that it is difficult (?) or impossible (?) to correctly process files such as the knuth text and for that matter any other letter text that contains regular Context commands.
Nevertheless, for the moment this problem remains unsolved.
What would you advise as the next step?
Should the letter be somehow set-up outside xml setups rather than inside? Should the letter texts (and a specific knuth sample text) be reformatted as xml?
So: you want to import the letter texts from an external file. Easiest solution: instead of simply \input knuth, try this: {\pushcatcodetable \catcodetable\ctxcatcodes\input knuth \popcatcodetable} As you can see, changing the catcode regime processes the file correctly. “Expansion” means something different in TeX speak. Other possibilities: write your letter body in xml, or write the letters in buffers and use \processTEXbuffer. Thomas
