I have a schema file that redefines a second schema file. When I open this eredefining schema I expect to have access to all the elements from the original schema as well as the redefining modifications. What Appears in the tree view is only the content of the redefining schema (so only those elements I am creatin gnew or those things from the base schema that have been modified.
For viewing purposes the tree view should show the combined content as if it was a single file. For editing I suppose you have to only show the content of the redefine file, but I would really expect some special handling when a redefine is involved.
