I've played around a bit today and the result is this:
http://people.freedesktop.org/~whot/Wayland/tmp/en-US/html/

I've copied over the Wayland Architecture page from the current website just
to have a proper chapter in there, the protocol documentation generated from
a modification of the xsl. 

The whole lot is generated with publican, I've been assured that publican
can also produce pdf, epub, etc. And the source was relatively trivial, even
for someone with little docbook experience.

With a bit of targeted styling, I think this could become quite useful but
before I invest any more time in this I'd like to hear a yay/nay.

Cheers,
  Peter
