My understanding it is done in client side as all XSLT transformation.  
Of course, server can do XSLT but will be for a different purpose.

Nevertheless, it still doesn't matter. httpRange-14 doesn't care about 
the content type of a returned representation.  It only cares about the 
response code. 

For any http-uri "x", if

(1) x respond 200
(2) And there is an assertion "x a web:NonInformationResource" (I don't 
know who should define it, Tim says AWWW won't. So, I guess anyone can 
do it in their own way).

Then, by httpRange-14, it results in a contradiction.
