Well, it depends on what "on the fly" compression mean. The server can 
associate a resource with an uncompressed file, and compress it on the fly 
for every request and send it with Content-Encoding: gzip (not efficient, 
I agree but doable). The resource is not synchronized with the actual 
bytes stored on the disk.
The fact that the spec talks about "SVG data" makes me think "entity 
body" and not "http message". But if other people have other 
interpretations, it should indeed be clarified.
