Maybe only your preferred viewers did not care about it yet, resulting in the wrong impression, that nobody at all cared. There were some implementation tests for SVG tiny 1.2, including several programs, which implemented SVG tiny 1.2 successfully enough, that it became a recommendation ;o) For example Opera at least interpretes audio and video and animation (but still with some bugs) - in general Opera interpretes parts of SVG tiny 1.2. Testing new issues and issues deviating from SVG 1.1 I got the best result with 133 of 335 test cases for Opera 10.60/ 11.00. As for SVG 1.1 the current Opera 12 seems to have some regressions for SVG tiny 1.2. Best results for audio with Opera 9.50 alpha/beta/ 9.52/ 10.0 alpha/beta/ 10.0: 26/31 One can see video for example with Opera 10.60/ 11.00/12.00, but most of my test cases Opera unfortunately fails due to problems requiredFormats switches (as for 'HTML5' for the same reasons there is no video format required, therefore one has to find a format, that is interpreted to continue with the test, Opera claims to interprete (animated) GIF, but ignores this for video). If one does not care about alternatives and choses specific video formats like OGG, one can see video including declarative timing and interactivity (but sometimes problems occur due to some bugs: missed events, sometimes no repetitions, ignoring begin times etc). There were other companies active within the development of SVG tiny 1.2 - I do not have access to their programs, but they have successful implementations as well. I think, there is an implementation report available. Unfortunately the SVG working group did never finish the test suite for SVG tiny 1.2. Because SVG tiny 1.2 is implemented at least in parts, explanations and examples are available in tutorials (as the german wikibook about SVG). Olaf
