Hello www-svg, Just to clarify about versions: For Xpath, it is XPath 1 that is being considered (or a subset). XPath 2, while more powerful, is also harder to implement and larger and newer, and not currently being considered for this task in sXBL. XML Path Language (XPath) Version 1.0 W3C Recommendation 16 November 1999 http://www.w3.org/TR/1999/REC-xpath-19991116 For Selectors, it is (CSS3) selectors. This is needed for the 'nth-child', 'not' etc functionality. CSS2 selectors (as implemented in SVG Full and SVG Basic, and by modern HTML browsers such as Firefox, Opera, Safari etc) would not be powerful enough and CSS1 selectors (as implemented in IE/Win) not nearly powerful enough. Selectors W3C Candidate Recommendation 13 November 2001 http://www.w3.org/TR/2001/CR-css3-selectors-20011113/ In both cases, there is an additional choice between implementing the full thing and implementing some subset. -- Chris Lilley mailto:chris@w3.org Chair, W3C SVG Working Group Member, W3C Technical Architecture Group
