Why isn't there a need for compatibility between browsers and (at least some)
non-browsers?  Clearly some implementations might have entirely different
needs, but that's why there's such a thing as a "SHOULD" requirement
<http://tools.ietf.org/html/rfc2119>.  Alternatively, the media fragment spec
could explain how it's expected to work in browsers and browser-like
implementations, without requiring that behavior of other implementations. 
HTML5 does this in its Rendering section.

In particular, I'd expect the same URL to be interpreted in essentially the
same way if I open it in a dedicated movie player (that supports opening URLs)
and if I open it in a browser tab.  If the browser starts at the fragment start
time and the movie player doesn't, for instance, I'd regard the movie player as
broken.

What HTML-specific requirements are needed in addition to those requirements?
