Well besides the fact that fragment ids cannot start with a number
nor contain a colon, you have to consider the problem of multiple
unequal representations. In this example equivalent content is not at
the same time offset. Clicking the link should take you to the
relevant place whether the UA is rendering the video, the audio or
the transcript:
<p>You <a href="#gegenschein">see the gegenschein</a> if you really
squint.</p>
<video src="video-with-visual-splash.mpeg">
<fragment-position for="#splash" time="00:00" />
<fragment-position for="#gegenschein" time="02:13" />
<audio src="audio-with-spoken-splash.aiff">
<fragment-position for="#splash" time="00:00" />
<fragment-position for="#gegenschein" time="02:24" />
<!-- transcript fallback -->
<section id="splash"><p>Produced by Foo Corporation</p></section>
…
<section id="gegenschein">
…
</audio>
</video>
