  Yes, by default it uses HTTP/1.1, which introduced chunked
transport.  I think using HTTP/1.1 is not really limitating in,
you know, 2012.

  If chunked transport is the root of the problem, then you have
two possible solutions: using HTTP/1.0, or disabling chunking.
You must be able to do either of them by setting the appropriate
system properties (the EXPath HTTP Client uses the Apache HTTP
Client 4).  Setting HTTP/1.0 can also be done, as you found, by
setting http:request/@http-version to "1.0".

  Just a word about the difference between both approaches: using
properties is probably better if your environment is limited to
HTTP/1.0 (e.g. because of a limited proxy), setting the HTTP
version on http:request is propbably better if the request itself
is limited to HTTP/1.0 (e.g. the example you found in the sources
because the *target web server* does not understand 1.1).

  Yes.  The corresponding spec has not been released yet.  There
was already an undocumented attribute to set the HTTP version,
but it was named @http.  It was renamed to @http-version when it
was added to the spec (well, to its unreleased yet draft).

  Exact.  Will announce the new release on the EXPath mailing
list once it's ready (by the way, there are more chances I see
your emails more quickly on the EXPath mailing list than here,
just in case...)
