One week is very little time to get public comment from other 
interested parties.

Please edit the wiki and remove the original Format and make the Alternative
Format the only format. The original Format has been superceded.

I also haven't figured out whether this header is included in every ogg 
packet or just the stream. From what I know of the Ogg container format
the stream cannot be decoded if the file header is lost. Therefore adding 
header data to each packet is just redundant.

There is also no discussion on the wiki on how data is packed into an
ogg packet. A sensible constrain would be that an ogg packet cannot
be constructed with a partial frame (ie the samples for all channels 
for a single sampling period).

I repeat, we need to correct and complete the spec, remove all 
contradictory and/or wrong information and then ask for comments from
others.
