Description barthanssens 2009-12-18 21:38:32 UTC 
Apparently OOo 3.1.1 doesn't support urn:-style attribute values (ODF 1.2 part 
III cd1) for manifest:checksum-type / manifest:algorithm-name / manifest:key-
derivation-name just yet.

I've created an encrypted ODT with values SHA1/1K / Blowfish CFB / PBKDF2 and it 
opens just fine in OOo, but replacing the attribute values with urn:oasis... 
seems to fail (OOo opens with a warning that styles.xml contains a Format Error 
at 1,1)

When there is any disparity between the default ODF 1.1 encryption methods supported by OpenOffice.org 3.3.0 and earlier, the package is opened as if there is no encryption.  The result is the styles.xml Format error with that is presumably a consequence of attemptiong to access the ciphertext (a binary file) as if it is unencrypted XML.

These tests need to be repeated with an Apache OpenOffice 3.4 developer snapshot or release candidate.
