Formatting problems above - the " should line up I think... also
"diskreservations" will look odd.
That's not what would be written. This is what would be:
error: cannot modify field 'reservations' of the disk
or translated:
fehler: Das Feld 'reservations' kann nicht geändert werden
IIRC it was discussed in v1 too. The idea is to have 'reservations' not
translated because it refers to the XML element name. However, the rest
of the error message can be localized.
