--- Comment #11 from Eike Rathke <er...@redhat.com> --- (In reply to Mike Kaganski from comment #10) > where some "unknown" element appears as a child of a known > element (attachment 173946 [details]), those should be silently ignored, as > we always do elsewhere (OOXML), implying that those may be some > unknown/unimplemented format extensions. That's not the case here though. The structure check knows that the <x:WorksheetOptions> element MUST appear nested in the <Worksheet> element. It does not check for unknown elements. -- You are receiving this mail because: You are the assignee for the bug.
