24621 2014-02-11 17:10:01 +0000 [xslt 3.0] Incorrect Notes re dynamic use of current-group() and current-grouping-key() 2014-02-16 19:37:44 +0000 1 1 1 Unclassified XPath / XQuery / XSLT XSLT 3.0 Last Call drafts PC All CLOSED FIXED P2 normal --- 1 mike mike cmsmcq public-qt-comments oldest_to_newest 100300 0 mike 2014-02-11 17:10:01 +0000 Under both current-group() and current-grouping-key() (14.2.1/14.2.2) we have the note The function is classified as focus-dependentFO30, which means that it cannot be used with higher-order functions. Specifically, current-group#0 will not be recognized as a function literal. This Note is no longer true. The rules were changed so that focus-dependent functions can be invoked dynamically. The closure of the function captures the context value at the point the function item was created. We should either delete the Note, or replace it by one that reflects the current specification. 100532 1 cmsmcq 2014-02-13 13:47:37 +0000 We discussed this in Prague and agreed with the analysis. 100717 2 mike 2014-02-16 19:27:38 +0000 The Notes have been updated. 100718 3 mike 2014-02-16 19:37:44 +0000 The analysis in the original posting is not quite correct; as a result of our decision on bug #23631, any dynamic function call that invokes current-group() or current-grouping-key() directly or indirectly behaves as if the relevant context values are absent, that is, it raises a dynamic error.
