Not really -- HTTP/1.1 has transfer encoding, which is applied after ranges
(it also has the advantage(?) of compressing the range metadata,
eliminating the cost of all those duplicate 'Content-Type' headers). A
before-content-coding range request doesn't really make sense, especially
if you're not applying C-E dynamically (assuming the server has an
unencoded representation handy, assuming that encoding the range is somehow
equivalent to encoding the whole, etc.).

I think the C-E/Range request issue is unique to HTTP/2, except that nobody
seems to have implemented T-E in HTTP/1.1.

I see.  In that case, why not XML?  ;)
