This is an important area but it would be easier to take the proposal more seriously if the proposal took XML and XPath more seriously. Adding the RANGE keyword to XPath [1] - to a language that has freedom from keywords as one of its core values - is an abomination. And the authors must be keen on manual query entry, since it appears that the pseudo-XML element constructor [2] has been carefully designed to break any XML-aware tool. All in all it seems to me that XSLT with some exslt extensions would be far better placed to build up maximum commonality than the approach proposed so far. Francis.
