Problem

In SDLXLIFF there may be tags in the target segment (and only in target) that look like this:

{{<target>
            <mrk mtype="seg" mid="3">
              <mrk mtype="x-sdl-location" mid="84dab49c-6853-4f36-876f-d5102c3f2921" />
              Starter og generator | Nye dele uden depositum - nu med 3 års garanti ✓ Gennemprøvet kvalitet ✓ Nem håndtering ✓ Fordelagtig pris ✓
              <mrk mtype="x-sdl-location" mid="434ef078-bac1-4692-969d-d4a592db45c7" />
            </mrk>
          </target>}}

After import they look like this in the editor:

Although the mid is unique, after import the tag is a duplicate and will lead to errors on saving the segment.
