[MarkLogic Dev General] MarkLogic XQuery Tag Library and JSTL XMLTag Library

Wed Apr 4 13:11:47 PDT 2007

Fixed my problem by downloading versions of standard.jar and jstl.jar  
newer than the ones included in the ML Tag Library download.   The  
output of from the xq:query tag parses nicely with x:parse and I can  
use x:out to select nodes in the XML document.
