The events with names: "endEvent", "beginEvent" and "repeatEvent" [1]. The attributes that correspond to these are "onend", "onbegin" and "onrepeat" respectively. Due to how the event-value syntax[2] works in SVG animation elements the event names can't be changed without conflicting with the sync-base value syntax[3]. I wish the event names were consistent with the pattern used for event handler content attributes, but they're not. In SVG2 most of the events with "SVG" event name prefixes have been removed[4], e.g "SVGLoad" is now a plain "load", which means they follow the pattern for event handler content attributes. SVGResize, SVGScroll and SVGZoom still remain to be fixed in the spec. Of these only SVGZoom lacks an existing unprefixed counterpart, so that would be a possible addition to GlobalEventHandlers with the event name "zoom". My question is: what should be done with the SVG specific event handlers? Should they be added to GlobalEventHandlers, or should they be just on SVGElement? This was ACTION-3542 (SVG WG).
