Description

I'm creating this jira issue, to track implementation of XPath 3.1 function item "inline function expression" processing.

Also to implement as part of this jira issue, XPath 3.1's higher-order functions like fn:for-each, fn:filter, fn:fold-left, fn:fold-right, fn:for-each-pair, fn:sort and "dynamic function calls" that make use of function item inline function expressions.

I've written little bit of code for this, that has been committed to XalanJ dev repos's branch xalan-j_xslt3.0. Few related working test cases for these implementation aspects, have been committed as well to the same XalanJ dev repos's branch.
