Description

I am not able to use the new fn:all function with SaxonCS 11 EE, both from XSLT 4 and XPath 4 I run into an exception "System.ArgumentOutOfRangeException: Index was out of range. Must be non-negative and less than the size of the collection."

Stacktrace for some C# test bed to run "XSLT 4":

Unhandled exception. System.ArgumentOutOfRangeException: Index was out of range. Must be non-negative and less than the size of the collection. (Parameter 'index')

It is run against the XSLT

C# code:

using System;

using Saxon.Api;

namespace SaxonCSRunXSLT4
{
    class Program
    {
        static void Main(string[] args)
        {
            var processor = new Processor();

            processor.SetProperty<bool>(Feature<bool>.TIMING, true);

            var xsltCompiler = processor.NewXsltCompiler();

            xsltCompiler.XsltLanguageVersion = "4.0";

            XsltExecutable xsltExecutable;

            using (var fs = File.OpenRead(args[0]))
            {
                xsltExecutable = xsltCompiler.Compile(fs);
            }

            Xslt30Transformer xslt40Transformer = xsltExecutable.Load30();

            if (args.Length == 2)
            {
                using (var fs = File.OpenRead(args[1]))
                {
                    xslt40Transformer.ApplyTemplates(fs, processor.NewSerializer(Console.Out));
                }
            }
            else
            {
                xslt40Transformer.CallTemplate(null, processor.NewSerializer(Console.Out));
            }
        
            Console.WriteLine();
        }
    }
}
