The argument I've heard the most is that since XPath is more complete and more general it would have performance issues compared to Selectors which were pretty much designed just for CSS (which is why they are almost never reused outside). I haven't seen numbers to back that up, but I would tend to believe it could be true. I do very much like the intent of bringing XPath and Selectors together though. W3C made a very serious mistake for which we are still paying the price when it allowed for both to be developed separately, and anything done to bring them back together can only help. I'm not convinced that merging the syntaxes in the way you propose is the way to go. I have been thinking along the lines of defining a CSS-compatible subset of XPath (since Selectors are largely a subset, with very little that's not in XPath or couldn't be expressed in it) so that one could use either in the same context with implementations only having to deal with different syntaxes. I'm not sure what the steps beyond that would be, but any step towards better integration would be helpful. -- Robin Berjon Research Scientist Expway, http://expway.com/
