[Speaking on behalf of reviewers from IBM, not just personally.] Section 2.1.2 The definition of the "Current date and time" component states, "If invoked multiple times during the execution of a query or transformation, [fn:current-date, fn:current-time, and fn:current-dateTime ] always return the same result." XPath should only impose this requirement for a single expression. It is up to the host language to impose this sort of requirement across multiple expressions (like a transformation in XSLT). In addition, section C.2 indicates that the scope of "Current date and time" is "global", which "indicates that the value of the component remains constant throughout the XPath expression." That contradicts the statement quoted in 2.1.2. 2.1.2 should be changed to be consistent with C.2 Thanks, Henry ------------------------------------------------------------------ Henry Zongaro Xalan development IBM SWS Toronto Lab T/L 969-6044; Phone +1 905 413-6044 mailto:zongaro@ca.ibm.com
