My point here was that stream structure version 0 pages (the current
ogg spec) are a strict subset of stream structure version 1 pages in
my proposal. (It could be so in yours too.) The new flag values are
chosen so that if they are set to zero as they are in version 0 pages,
the header can be parsed just like a version 0 page, which hopefully
simplifies implementation.
