When dealing with timed content - shouldn't there be a relative URI meaning
from the current time to the designated time. I'm thinking of something
Which would be used to continue a piece a playing media up to the 40 second
point and then stop.
This could prevent a fetch by the UA to the start of the media fragment
which could be especially useful if the media is marked as no-cache.
I'm thinking an article could outline links on a page each of which would
cause a related video to continue playing up to the point specified in the
link and then stop - giving the reader a chance to catch up.
This also brings up the matter of link targets. Shouldn't I be able to do
something like this:
<a href="#,50" target="presentation">Next Slide</a>
