Hi, I'm trying to typeset a BNF grammar. The module t-bnf appears to not work with mkiv.
http://ctan.math.washington.edu/tex-archive/macros/context/contrib/context-bnf/doc/context/third/bnf/t-bnf.pdf tex error > tex error on line 157 in file /Users/acailliau/context/tex/texmf-modules/tex/context/third/bnf/t-bnf.tex: !

Here is a minimal example: \usemodule[t-bnf] \starttext \startbnfgrammar[] <exp>: <num> | <num> "+" <num> <num>: "1" | "2" | "3" | "4" | "5" | "6" | "7" | "8" | "9" \stopbnfgrammar \stoptext Thanks in advance, Antoine
