--- Comment #10 from Eike Rathke <erack at redhat.com> ---
This is not a duplicate, though similar or related. Bug 104250 is about the
<sheetProtection> element, whereas this is about the <fileSharing> element.

This will need to support the <fileSharing> element with algorithmName,
hashValue, saltValue and spinCount attributes and feed those with the password
to be entered to the proper hashing/digest implementation.

Currently only the reservationPassword hash and readOnlyRecommended attributes
are supported, which are not present here. If reservationPassword hash or
readOnlyRecommended=true were present, the document would always be opened
read-only. A password dialogue unprotected write open is not implemented.
