Don't listen to that. While it's technically true, (a) most users don't
redefine catcodes or internal macros anyway (and imho there are fewer
reasons to do such hacking in ConTeXt than in LaTeX) and (b) for the
sake of syntax highlighting/parsing by external tools, you have to
assume some sanity anyway (so that you don't have to reimplement full
TeX instead of writing some parser).
That said, I know little about regular languages, BNF notations
etc. (with the exception of some _practical_ experience with regexen),
so I'm not sure about what I've written above. But I would guess that
if you make some (reasonable) assumptions about catcodes and command
syntax, writing a BNF style grammar for (at least some part of)
ConTeXt might be pretty doable.
