Hello group, How should an empty SVGTitleElement of an element be treated, if its parent node has a non emtpy SVGTitleElement? <g> <title>title of g</title> <rect> <title></title><!-- empty string as title here --> </rect> </g> Firefox and Chrome seem to eliminate the rectangles empty title element and resolve the title element of the group as tooltip instead [1]. Is this the desired behaviour? The Spec at http://www.w3.org/TR/SVG/struct.html#TitleElement is not clear about this case, it only states: "If user agents need to choose among multiple ‘desc’ or ‘title’ elements for processing (e.g., to decide which string to use for a tooltip), the user agent shall choose the first one." It does not say, whether empty titles should be stripped prior to making this choice or not. The consequence of this behaviour is, that you are not able to "reset" titles (and thus tooltips) as soon as you have specified a title on the parent node. Setting <title> </title> seems like a poor hack to overcome this situation. Any thoughts on this topic? greetings Klaus [1] http://svg.cc/posts/emptyTitleBehaviour.svg -- Klaus Förster Department of Geography University of Innsbruck A-6020 Innsbruck, Innrain 52
