Idea for SMIL syntax: Control of progression through hyperlinks

Hi, I wanted to post an idea for future SMIL attributes that would allow for
further control of a presentation's progress and playback, if this is the
place to do such.
My idea conceives of tying SMIL's timing mechanism with the usage of
intrapage hyperlinks to allow for two options of intermediate progression
control over a presentation: "time-based" and "textsection-based".

Time-based progression control would link the presentation proper with an
explicit summation of the total time of the presentation's progression.

Textsection-based progression control, another optional method that can be
used in conjunction with time-based control, would allow for the
presentation to be controlled using area links.

Finally, a stationary progress slider could be constructed out of markup (be
it XHTML, SVG or your run-of-the-mill user interface markup language with
CSS styling) and can tie into both the time and textsection properties of
the entire animation. I imagine the syntax being something like the
following:

<play fulltime="75s" begin="Begin" end="End" indicator="indicator.svg"
progresscolor="red" ><video>.....</video></play>

I think that this should be accomplishable through markup rather than
forever relying only upon scripting to get a proper progress control method
for markup presentations (particularly SVG slideshows and animations) and
multimedia.
