It would be easier for user to Navigate Broken References if the releated nodes
can be marked with something like a little Red-Cross icon, like bpel project.

Right now, as a user, if you modify a schema file that is referenced by other
files, you have to remember all these files, open them one by one to fix the
Broken Reference issue manually. It is not very user friendly with current
design. Because:
1. Without marking those files, some of the files may be missed.
2. Without marking the nodes, it is not easy to figure out where to fix the issue.
(See the attached screen shot NeedToMarkBrokenReference.png. The blue-ellipses
are the places that I would suggest to be marked. The red-ellipse is the place
that I would suggest to be highlighted.)

Attached screen shot BrokenReference.png is a bpel sample. I modified one of the
import namespace, Red-Cross icons are added for the related nodes in the
Navigator window. It helps user to find issues and fix them.
