Blinking time colon

[jeremiahlee]

I'm trying to make the colon in the time blink on and off.

This is what I came up with. Is there a better way?

<text id="timeColon" text-anchor="middle" text-length="1" opacity="1">:
    <animate attributeName="opacity" begin="load+1" from="1" to="0" dur="0" repeatCount="indefinite" repeatDur="2" />
    <animate attributeName="opacity" begin="load+2" from="0" to="1" dur="0" repeatCount="indefinite" repeatDur="2" />
</text>

Also, three things in the documentation need to be improved:

1. I struggled to get `repeatDur` working because there is no example in the documentation and it is unclear what its relationship with `repeatCount` is. The documentation says "repeatCount or repeatDur", but I think it means "repeatCount and optionally repeatDur"?

2. The values for `final` are listed in the documentation, but there are no definitions for what `freeze`, `remove`, `restore`, and `keep` mean as attributes.

3. When does the `repeatDur` start? At the time of the start of the animation or the conclusion of the animation?

If that's working for you, then it's all good. You could also just show/hide the element in JS.

Thanks for the documentation feedback, I've logged those for a future update.
