If you click two subsequent times on the rectangle, you see an animation toggling on and off:

I want that to work as many times as you may want, but it only works once; afterwards the rotation start point for the first click is for some reason shifted by -90 deg, as you'll notice from upon the 3rd click. Any ideas?
UPDATE
I noticed the following, if that may help to solve the problem (still unable to solve it): Try out the following with the snippet above:
A) Click on the rectangle once
B) Click on the rectangle again, to get the label back to its original position
C) Before clicking on the rectangle for the third time, copy the four animateTransform tags inside the text tag into a js variable let's say yourSavedAnimateTransformString, then delete them from the markup, e.g. via
document.getElementsByClassName("timeline-project-label")[0].innerHTML =
document.getElementsByClassName("timeline-project-label")[0]
.childNodes[0].outerHTML +
document.getElementsByClassName("timeline-project-label")[0]
.childNodes[1].outerHTML;
, then reinsert them at the exact same place with js, e.g. via
document.getElementsByClassName("timeline-project-label")[0].innerHTML +=
yourSavedAnimateTransformString
Then, click on the rectangle a third and a fourth time, and you'll see that it will work for the third and fourth time without refreshing the page, but fail again for subsequent clicks, unless you repeat this delete-re-insert procedure on every 2nd click on the rectangle, which is a rather hacky not-solution to me.
I supposed that this info may be useful to solve my problem, as it indicates that my problem's somehow related to an unaccessible tracked state of the present animateTransform tags, which can be eliminated by renewing these tags on every 2nd click.
As this is not a real solution, I'd still really like to understand what's going on here..?
UPDATE 2
How come that the snippet above actually does not ainmate the transforms AT ALL in Safari?? According to the specs, animateTransform is supported for all except IE... (for which I'll use Fakesmile when done..)?
I've only noticed it now; you may check my problem in FF and Chrome, where the snippet behaves as described.
Doing it programmatically via document.getElementById("activate_project_10").beginElement() does actually work, but is this really necessary? Which is the standard approach for svg animatransforms in safari?
Okay, found a solution which works in FF and Chrome. The principal thought was to overwrite, after finishing the last animation of inactivate_project_10 animation, the state of the transform property with the initial value, before triggering the first one of the activate_project_10 animation. All this while thus using replace instead of sum as the value of additive for the last resetting animation, while using accumulate=sum to assure that the accumulated (thus actually the resetted) value is taken for the reset.
And this actually worked:

The main modifications were:
changed the dur in the two main animateTransforms (inactivate_project_10 and activate_project_10) to the same time as the combined translation + rotation animations of 0.5s.
added the last animateTransform tag to reset the transform state to the initial state to be able to toggle the animation in an endless loop of clicking. Use a particularly short duration (0.01s used) to reset as fast as possible when finishing a toggle cycle, to quickly be ready for the next one, if triggered again.
Yet, I'd still like to know why this is not working AT ALL in Safari..? Even if you use beginElement(), that only works for the first two toggles, and then stops working..
Trying to animate an SVG element with the skewX. It works, however, not exactly the way I want it to.
Now: the bottom part moves to the left
Goal: the upper part should move to the right instead (and bottom stays in place)
I tried with transform-origin but it didn't work. Any ideas how to solve this mystery?

Use another transform to move the whole thing to the right at the same time as the bottom moves left.

The difference of the following code?
Why the result is different from?
I thought it was the same.
However, different results when the cell actually animation.
<svg width="1000" height="1000">
<circle cx="10" cy="10" r="10">
<animate
attributeType="XML" attributeName="cx"
dur="10s" values="100; 200; 100"
repeatCount="indefinite" />
<animate
attributeType="XML" attributeName="cx"
dur="10s" values="0; 300; 0"
repeatCount="indefinite" additive="sum" />
</circle>
</svg>
<svg width="1000" height="1000">
<circle cx="10" cy="10" r="10">
<animate
attributeType="XML" attributeName="cx"
dur="19s" values="100; 200; 100"
repeatCount="indefinite" />
<animate
attributeType="XML" attributeName="cx"
dur="1s" values="0; 300; 0"
repeatCount="indefinite" additive="sum" />
</circle>
</svg>
Its not the time thats additive, if thats what you think, its the value of the attribute (cx).
As you have 2 animations running at the same time, cx will build up as a combination of whatever the values of cx are on each animation.
On the 2nd example. As one of the animations is only 1 second long, it will fluctuate very fast, on top of a slower animation.
If you forget about the additive for the moment, and just replace the 2nd cx value with cy on both, you will see why the animations are fundamentally different as well.
animateTransform is not working properly for me on safari (both Iphone and windows safari 5). Here is the fiddle. Compare it in Chrome vs Safari.

This is undoubtedly a bug, but what I'm hoping is that someone has had this same problem and found a workaround. Neither google nor SO has turned up this exact same issue for me. Here is the code:
<svg id="thesvg">
<defs>
<path id="Xprototype" d="M -20,-20 L20,20 M20,-20 L -20,20" stroke="blue"/>
</defs>
<g class="myelement" fill="transparent" elementnum="1" transform="translate(20 120)">
<use xmlns:xlink="http://www.w3.org/1999/xlink" xlink:href="#Xprototype"></use>
<animateTransform attributeName="transform" attributeType="xml" type="translate" to="20 120" dur="1s" begin="0" ></animateTransform>
<animateTransform attributeName="transform" attributeType="xml" type="translate" to="140 140" dur="1s" begin="1" fill="freeze"></animateTransform>
</g>

Anyone have any ideas? Thanks.
When trying to get SVG rendering in older IE browsers I've used the svgweb project.
Recently I've come up against bug 585 in svgweb.
https://code.google.com/p/svgweb/issues/detail?id=585&q=visibility
In the following example the rectangle stays hidden in IE but shows after one second in Chrome.
<set xlink:href="#testRect" attributeName="visibility" attributeType="XML" begin="1s" end="2s" from="hidden" to="visible" fill="freeze"/>
<rect id="testRect" x="0" y="100" width="300" height="150" fill="#A68064" visibility="hidden" />
I have found a workaround. Dynamically setting the fill or stroke of an element before setting the visibility results in the correct behaviour.
<set xlink:href="#testRect" attributeName="fill" attributeType="XML" begin="0s" end="1s" from="#A68064" to="#A68064"/>
<set xlink:href="#testRect" attributeName="visibility" attributeType="XML" begin="1s" end="2s" from="hidden" to="visible" fill="freeze"/>
<rect id="testRect" x="0" y="100" width="300" height="150" fill="#A68064" visibility="hidden" />
