[racket] How to disable cross-referencing in Scribble; why inside

Hi,

I want to use Scribble for documenting some non-Racket code and will
use the eval environment (yet to be done) along with it's nice
rendering and display.

I don't want scribble attempt to cross reference the language since it
will not be do-able and red-lines will appear all over.

How do I disable that cross-referencing in a case like this?

Sorry if I missed it in the docs.
