Re: Beta release of XProc-Z 1.0

Hi Florent!

Yes XProc-Z is in many ways like Servlex or Piperack or similar server
platforms. The key difference I think is the way in which the XProc
pipeline is connected to the HTTP protocol.

If I understand it correctly, in Servlex the HTTP request is parsed into a
sequence of XML documents of a custom (Servlex-defined) type, which are
passed to a pipeline. In other words, the HTTP protocol is converted into a
custom protocol for connection to the pipeline.

Whereas when XProc-Z receives an HTTP request, it passes it to the pipeline
in the form of a c:request document, to which the pipeline is expected to
respond with a c:response document. In other words, an XProc-Z pipeline
uses XProc's own "native" HTTP protocol binding, just like the
p:http-request step.

PS Straight after posting that release, I discovered a regression error in
the downloading of binary files (base64 decoding) which I'm now fixing,
while kicking myself for not having a proper test suite.
