If we have an element in DEFS referred by at least 2 USE elements and the element contains SMIL animations with begin/end triggers referring the element itself, the animations are applied to all USE occurrences. jsFiddle explaining the behaviour http://jsfiddle.net/maros_urbanec/vzYZp/3/ Firefox starts the animation on the current USE element only.
It's Firefox that'a wrong. I think we have bugs in our bugzilla covering this.
