That's what I do now.

But in JSON case there are the same arguments. JSON is data 
serialization oriented markup language and engines need to know whether 
the string is to be interpreted literally or parsed like JSON.

Agree. CSS and Javascript aren't neet to be RDF datatypes. But CSV (and 
TSV) could be considered.
