I've worked around this using nix-repository-manager by intorducing
regions, it looks like this:

# REGION AUTO UPDATE: { name="haxe-unstable"; type="svn"; url="http://haxe.googlecode.com/svn/trunk"; }
src = (fetchurl { url = "http://mawercer.de/~nix/repos/haxe-unstable-svn-6387.tar.bz2"; sha256 = "18bcdf23d7ed32d0bafaf4a0acbc9715ea6c30ae22642cb8b797c870098835c0"; });
name = "haxe-unstable-svn-6387";
# END

its not perfect, but does all I need:
  - it documents where to get updates from
  - it knows which piece of code gets updated
  - it inserts that piece of code
  - still simple, everything is in one place without too many additional
    files.

But its only my quick and dirty way to cope with some update problems.
