Note: we can *add* methods to existing interfaces from backwards compatible
version to version. We do not try to maintain binary compatibility with WiX
toolset releases. In other words, if someone takes a new drop, they are
expected to rebuild all of their stuff against the new drop.
Now, when they recompile against a backwards compatible release everything
should just build and work. If not, then we should fix that as quickly as
possible.
