17031 2012-05-10 14:28:59 +0000 <foreignObject> is wrongly marked as invalid when outside <switch> 2012-05-10 14:28:59 +0000 1 1 1 Unclassified HTML Checker General unspecified PC All NEW P2 normal --- 1 xn--mlform-iua mike+validator www-validator-cvs oldest_to_newest 67556 0 xn--mlform-iua 2012-05-10 14:28:59 +0000 Problem: The HTML5 validator stamps <foreignOBJECT> as invalid, unless is occurs as child of the <switch> element. By contrast, W3's SVG specific validation service considers it as fully valid even without the <switch> element. What does the spec say? Well, according to HTML5, then HTML5 supports SVGTiny12. And SVG Tiny 1.2 says: ]] Usually, a 'foreignObject' will be used in conjunction with the 'switch' element and the 'requiredExtensions' attribute to provide proper checking for user agent support and provide an alternate rendering in case user agent support is not available. [[ See: http://www.w3.org/TR/SVGTiny12/extend.html#ForeignObjectElement Thus, according to the spec, there is perhaps a recommendation to use <switch>, but there is no requirement to use <switch>.
