I agree with Lyman and vapilot2004 conclusions for that reason :
CVR and Witness report are in NATURAL LANGUAGE , a NON-CONTEXT-FREE language. So you cannot replace or modify them.
Not modified CVR and Witness report bring us not only the FORMAL CONTEXT-FREE words but also the Context which helps us to understand the words and semantic of NATURAL LANGUAGE of the Crew and of the Witness.
It is the main difference between Human and software production.
