> Does it support infinite loop?

Yes, by setting the repeatCount or repeatDur attribute of the <animate> tag to "indefinite". Notably, since <animation> tags effect individual attributes and not the image as a whole, different parts of the image can be on different animation cycles and don't have to add up to some small common multiple.

Yes

https://developer.mozilla.org/en-US/docs/Web/SVG/Reference/E...

  <svg viewBox="0 0 10 10" xmlns="http://www.w3.org/2000/svg">
  <rect width="10" height="10">
    <animate
      attributeName="rx"
      values="0;5;0"
      dur="10s"
      repeatCount="indefinite" />
  </rect>
  </svg>

SVG embeds Ecmascript (or Javascript as the rest of the world knows it): https://www.w3.org/TR/SVG11/script.html

So not only do you get all the animation support from the attributes, you can fill in anything you need from scripting.

Yes it does.

https://www.w3schools.com/graphics/svg_animation.asp - Has some examples, you may need to refresh to see some of them (ones that don't repeat) in action as you scroll down the page.
