> OIV's ReverseXML processor cannot reconstruct some snapshot details.
> Specifically, <fileDiff> should contain a <snapshotCopy> and <blocks> field,
> but does not. <dirDiff> should contain a <snapshotCopy> field. OIV also
> needs to be changed to emit these fields into the XML (they are currently
> missing).
