WCAG** discusses moving content and recommends that the user should  
be able to pause SVG SMIL animation.
Opera and Safari are the two native SVG1.1 browsers with support for  
How is this achieved?
is there a script mechanism?
does SVG1.2 have a different method in this respect?

**Guideline 7. Ensure user control of time-sensitive content changes.
Ensure that moving, blinking, scrolling, or auto-updating objects or  
pages may be paused or stopped.

*7.3 Until user agents allow users to freeze moving content, avoid  
movement in pages. [Priority 2]
When a page includes moving content, provide a mechanism within a  
script or applet to allow users to freeze motion or updates. Using  
style sheets with scripting to create movement allows users to turn  
off or override the effect more easily.
