Description Remy Suen

1. Open the 'Properties' view.
2. Open an XSD file.
3. Switch to the 'Source' view.
4. A CCE is thrown.

From the code a downcast to StructuredSelection is made directly from ISelection. This seems wrong but doesn't occur on 3.x for whatever reasons. Will need to cross-check what's going on on that side.

Actually, the problem occurred while I was using 3.x inner with minimal dependencies.
