RE: How can one get the name of a template or function

If you're prepared to grovel around the depths of Saxon internals, you can
write an extension function 


public static String getTemplateName(net.sf.saxon.expr XPathContext context)
{
    try {
       return context.getOrigin().getObjectName().getDisplayName();
    } catch (Exception err) {
       return null;
    }
}

and call it without any arguments as xx:getTemplateName(). Not tested. It
will only give the template name if it was invoked using call-template.
Should probably work for function calls as well.
