Well, Java can "watch" a directory for changes see e.g.
https://docs.oracle.com/javase/tutorial/essential/io/notification.html
so it is certainly possible to implement something in Java but I have no
idea how such a function would fit into Saxon's use of Java extension
functions to XSLT/XPath/XQuery; perhaps Michael Kay shows up later and
can tell you more.
