[wix-devs] Defining "forward-compatible bundle"

Look at the RelatedBundle element in the wix schema.  I author a
RelatedBundle element using the Detect option in each bundle I spin up.  I
also create 'Addon' bundles which also have a ReleatedBundle element with
the option 'addon' and the guid defined for the target bundle.  There are
also 'Patch' and 'Upgrade' types of 'related' bundles.

The different types of related bundles have different behaviors, after they
are installed when the base bundle is repaired, upgraded, or uninstalled.
I implement DetectRelatedBundle in my mba to implement business logic
required to assure that in my case the addon is appropriate for the
detected base configuration.  (I use the same mba dll in many different
types of bundles with business logic specific to a bundle's behavior and a
related view, keying off of the BundleTag.)
