Yes, I believe we could use this bundle as well. (or Xerces, etc) We just
need the XML APIs to compile against.

If you add a Foundation VM to your list of installed JREs and it is
correctly identified as an exact match to that profile, then you will not
get (for instance) the XML APIs for free (from the VM) so you need you have
another bundle in your workspace which can provide them.

If you don't have a lower profile (like Foundation) VM installed, then you
will not be effected because 1.4/1.5/1.6 VMs are considered to be
compatible and your bundles will still resolve and function correctly.

Here is a (probably a little out-dated) wiki page that we put together with
a bit more info on EEs and setting things up.
