I had to rename XSLTForms global Javascript objects to avoid name 
conflicts with frameworks: "XPathCoreFunctions" has been renamed 
"XsltForms_xpathCoreFunctions".

When defining an XPath function for XSLTForms, parameters casting has to 
be considered so I rewrote this function and added it to the others (the 
namespace is not correct... but it's the default one...):

     "http://www.w3.org/2005/xpath-functions ends-with" : new 
XsltForms_xpathFunction(false, XsltForms_xpathFunction.DEFAULT_NONE, false,
         function(string, postfix) {
             if (arguments.length !== 2) {
                 throw 
XsltForms_xpathFunctionExceptions.endsWithInvalidArgumentsNumber;
             }
             var s = XsltForms_globals.stringValue(string);
             var p = XsltForms_globals.stringValue(postfix);
             return s.substr(s.length - p.length, p.length) === p;
         } ),

Defining your own Javascript function is another possibility (parameters 
are always passed as strings):

     <script>
         function js_ends_with(s,end) {
             return s.indexOf(end, s.length - end.length) !== -1;
         }
     </script>

XPath ends-with() function is now supported in r566.

Thank you for your feedbacks!
