Comment 41 for bug 1251394

Thanks, Mike. Streamlining++

The redundant definitions were added as a step toward addressing Galen's concerns from #26, i.e. that some stock index definitions will not match what we want to use for display data. The XPATH is identical because we never got around to actually creating the display-friendly definitions.

Also, why the return of the 'representative_field' column? That should no longer be needed with the new display_field_map table. If someone wants the title, it should be enough to ask for the display_field_map row whose name is 'title'.
