This would also be the behavior if a Tiny user | agent attempts to process a "Full" document which might have a value | like begin="10:00" rather than begin="600s", does it make sense to | discard the element immediately if the author really wanted to discard | it after 10 minutes? We discussed this several times, and have decided to keep the default begin value as '0s'. Of course, we thank you nonetheless for sharing your suggestion with us. In addition to the reasons stated above, it is the opinion of the SVG Working Group that an author sophisticated enough to use the discard element will be inclined to use resources such as the spec, where both the syntax and the purpose of the 'discard' element is clearly explained, such that authors will be able to understand at once how they should be using it. Even hackers will able to experiment with the attribute values to achieve their desired effect. Authoring tools, of course, can make the decision to set the value to whatever is most appropriate for the target device and UA. Thanks- Doug, on behalf of the SVG WG
