http://www.cs.york.ac.uk/fp/HaXml-devel/ which says that version's API "may be
incomplete, inconsistent, and liable to change". I'd call that "unstable", and
I wouldn't want to write code against unstable interfaces when I can avoid
You can't use the Hackage packaging choices as a model. Hackage and Cabal both
handle multiple coexisting versions gracefully, while Debian only allows one
version of a package on a system.

I'd recommend against that. There's no reason to continue breaking existing
packages. The 1.19 version should be called haxml-devel, following upstream's
