+Subject: vtkXMLDataParser: track `AppendedData` state explicitly
+Bug-Debian: https://bugs.debian.org/1064762
+Origin: upstream,https://gitlab.kitware.com/vtk/vtk/-/commit/3efa07ad277efe5c1d11a2ef2b907c095f68bbef
+Forwarded: not-needed
+
+Newer `libexpat` doesn't like being given the appended data after the
+artificially ended document anymore. Avoid pushing it through to its
+parser.
