This will break almost all existing clients. Most of them are not smart
enough to parse content-types according to MIME rules but will simply
determine that "text/html; version=2.0" is not a recognized content-type
and prompt the user to save the result in a file.

Of those clients I have handy, Mosaic 2.5b for X, Netscape 0.9b for X, and
Lynx 2.3b all do this. Only Arena 0.91b does the right thing.

If you want to test this, a simple file with that content-type is
available at <>.

It's a pity, because it's obviously the right way to provide versioning
information but existing software won't work with it.
