Hi!

Nice series!

I think it'd be a bit more conventional to rename docbook-xml-package to
'make-docbook-xml'.  It'd be nice if instead of having to have to
manually override the install phase for each version the generator would
handled that.  Perhaps it could also accept as an arguments a list of
the files to install, in the format understood by the copy-build-system.

This should reduce the template inheritance & overriding boilerplate
needed.
