Re: *Possible* additional use cases

Hi Ivan,

Thanks.  Is you plan to discuss these on the mailing list or have them be
topics for a future DPUB IG Call?

My first off the cuff reactions to each (from top to bottom, on a scale of
one [don't include] to ten [certainly include]) would be:

#1 - 7 (assuming the PWP has been authored in such a manor to provide this
data)
#2 - 2 (doesn't seem practical, given our online, offline, off-web use
cases; though perhaps there is an authoring time solution)
#3 - 5 (perhaps noble)
#4 - 9 (forward compatibility with the existing EPUB ecosystem)

Best,
   Garth
