Re: animateTransform has no default value for 'type'

1) I’m sorry, Firefox was the one I didn’t test. It appears like the default value is not implemented in Chrome, Opera, and Safari (IE/Edge I have no idea and honestly don’t care). That’s sad.

2) That was not what I meant. Maybe I didn’t explain precisely enough. I'll give an example:
I want this

<path d='M1 1 1 2 2 2 2 1Z'>
  <animateTransform attributeName='transform' type='translate' dur='7s' repeatCount='indefinite' values='0,0;1,0;1,1;0,1;0,0'/>
</path>
<path d='M2 2 2 3 3 3 3 2Z'>
  <animateTransform attributeName='transform' type='translate' dur='7s' repeatCount='indefinite' values='0,0;-1,0;-1,-1;0,-1;0,0'/>
</path>

to be expressible as this

<g>
  <animateTransform attributeName='transform' type='translate' dur='7s' repeatCount='indefinite'/>
  
  <path d='M1 1 1 2 2 2 2 1Z'>
    <animateTransform values='0,0;1,0;1,1;0,1;0,0'/>
  </path>
  <path d='M2 2 2 3 3 3 3 2Z'>
    <animateTransform values='0,0;-1,0;-1,-1;0,-1;0,0'/>
  </path>
</g>

So all the animation attributes which are identical for both <paths> I just want to have to write once.

Firefox implements correctly and executes a translation if 'type' is not specified (lines 9 and 15 in the example below). Chrome doesn’t. You can report the bug with Chrome, but I'm not sure if they care any longer.
