Thanks for these replies! Adding \unexpanded or \protected before \def
didn't fix the problem, and surrounding the definition with \unprotect ...
\protect didn't work either. But surrounding it with \pushcatcodetable
\setcatcodetable\ctxcatcodes ... \popcatcodetable worked.

I've never seen these commands before, but I gather from the existing
documentation that the current catcode governs which characters are treated
as special when a buffer is being processed. So here, it looks like I'm
temporarily switching from some other catcode set (it looks like in
publ-ini.mkiv, \catcode\commentasciicode\othercatcode gets invoked
in \publ_set_publication, so perhaps that's what's happening?) to the
default ConTeXt catcodes and then back.

Thanks again!

Joey
