Subject: [OASIS Issue Tracker] Commented: (OFFICE-2739) ODF 1.2 Part 3 4.8.5manifest:initialisation-vector underspecified

    [ http://tools.oasis-open.org/issues/browse/OFFICE-2739?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=22736#action_22736 ] 

Michael Brauer commented on OFFICE-2739:

The current text reads:

The manifest:initialisation-vector attribute specifies the byte-sequence used as an initialization vector to a encryption algorithm. The initialization vector is a BASE64 encoded binary sequence.

I'm fine with adding "There shall be enough bits in the value to satisfy the requirements of the specified algorithm.", but I'm not sure I understand what the other changes improve. I personally find "The initialization vector is a BASE64 encoded binary sequence." much more understandable, and are confused by the many "left-to.-right" and "left-adjusted" in your proposal. Aren't these details that are already specified by the BASE64 encoding itself?

I further think the note is not required. They make provide a few explanations, but a standard is not a documentation. We should use notes only where absolutely necessary.
