13.5 Time Manipulation

Very cool feature, but a few comments.

- The IDL is missing.

- You did not give a range or type for the values. You refer to both '0' and
'50%' as possible values. Must it have a percentage sign, unless it's value
is '0'? Can you use floating point units, such as '0.5' to indicate '50%'?

- You state that this can be used to slow down or reverse the playback speed
of an element; can it also speed it up, using a value like '150%'? 

- It's unclear whether this works for both animation of 'normal' graphical
elements ('circle', etc.) and for video playback? If it works for video,
what are the constraints, as regards streaming and such?

- In general, I would like to see attribute values presented in a manner
similar to attribute names (with a different color, of course). Something
like <span class="attribute-value">'50%'</span>. I think this would add to
the readability.

- The name for the 'speed' attribute is very general, and conflicts with a
possible 'speed' attribute I'm proposing in my BAM Spec. To avoid this, I
would recommend using  a more specific name such as
