Hi Folks, XPath is a non-XML syntax. XSLT, Schematron, and XML Schema 1.1 make heavy usage of XPath. The role of XPath seems to expand with each new version of these technologies. Why? Example: consider this XML snippet: <meeting> <start-time>08:00:00</start-time> <end-time>09:00:00</end-time> </meeting> In both Schematron and XML Schema 1.1 the co-constraint between the meeting's start time and end time is expressed using XPath: meeting/start-time lt meeting/end-time Why isn't this co-constrain expressed using XML markup? Why do we resort to non-XML syntax? Does it indicate an inherent limitation in the expressability of XML markup? Has anyone characterized this limitation? /Roger
