我收到了一个我想在HTML5项目中使用的SVG SMIL文件。我在使用SVG SMIL文件时并不熟悉，并且在打开文件时我可以看到它是XML格式的，并且我已经做了所有必要的更改以使其能够在HTML5中工作，但是它不通过W3C验证，我希望固定。SVG SMIL HTML5对于元素集上的属性填充，值为'none'
问题似乎是，使用value:none未通过HTML5中的验证，实际上它的重复次数是由w3c Bad value none for attribute fill on element set.报告的11倍。我希望你们中的一位明亮的火花可以指导我解决这个问题的正确方向你可以在下面看到我的完整代码。
