Right, it doesn't. That is because we realize this is substantially harder for irregularly shaped, multicolored graphics than it is with, for example, a focus outline around box-model content. Even something like xor, which is initially promising, fails against a background of a highly noisy dot pattern. So - it should, but its hard to test and hard to recommend a default highlighting scheme or schemes that is universally applicable without user or author intervention. We chose therefore not to make this a conformance requirement for Tiny. In SVG 1.2 Full, we address this by providing a way to style the focus highlight. This allows content authors to pick a method that will work well with the type of content they are creating in terms of shape, range of colors, contrast range and so on. Please let us know shortly if this response does not address your comment. -- Chris Lilley mailto:chris@w3.org Chair, W3C SVG Working Group W3C Graphics Activity Lead Co-Chair, W3C Hypertext CG
