Symptoms

 When creating an XQuery transformation for using within a BPEL 12c, the XQuery extension functions are unable to be accessed.

 For example, When trying to use the following function "xp20:format-dateTime()", an error message "The prefix 'xp20' used in the qualified name 'xp20:format-dateTime' can not be resolved" appears in the live issues window.

 If then insert a namespace declaration in the header of the XQuery file declare namespace xp20="http://www.oracle.com/XSL/Transform/java/oracle.tip.pc.services.functions.Xpath20", an error message "format-dateTime 'unknown function (or number of arguments (2) is wrong)'" appears.
