It's always worth quoting an error message in full even if it seems cryptic - it might make sense to someone else who knows the software better, or who has seen it before. It's also worth providing a little bit more of your code (what is "val", for example?), - preferably enough so that someone else can try running it - and indicating more precisely where the error comes from.

key and val are both strings - key is the parameter name and val is the parameter value. The full error message [Saxon.Api.DynamicError]: {"CCE"} Data: {System.Collections.ListDictionaryInternal} HelpLink: null InnerException: null Message: "CCE" Source: "saxon9api" StackTrace: " at Saxon.Api.XsltTransformer.Run(XmlDestination destination)\r\n at <<my stack>> TargetSite: {Void Run(Saxon.Api.XmlDestination)} What I really need is an example of working code passing parameters into a transform in Saxon .Net, but I can't find one anywhere. Is XdmAtomicValue the right thing to be using? It seemed to be the most appropriate XdmValue for me to use.

There's an example in the XsltExamples.cs program that's part of the saxon-resources distribution: /** * This shows how to set a parameter for use by the stylesheet. Use * two transformers to show that different parameters may be set * on different transformers. */ public static void ExampleParam(String sourceUri, String xsltUri) { // Create a Processor instance. Processor processor = new Processor(); // Load the source document XdmNode input = processor.NewDocumentBuilder().Build(new Uri(sourceUri)); // Compile the stylesheet XsltExecutable exec = processor.NewXsltCompiler().Compile(new Uri(xsltUri)); // Create two transformers with different parameters XsltTransformer transformer1 = exec.Load(); XsltTransformer transformer2 = exec.Load(); transformer1.SetParameter(new QName("", "", "a-param"), new XdmAtomicValue("hello to you!")); transformer2.SetParameter(new QName("", "", "a-param"), new XdmAtomicValue("goodbye to you!")); // Now run them both transformer1.InitialContextNode = input; XdmDestination results1 = new XdmDestination(); transformer1.Run(results1); transformer2.InitialContextNode = input; XdmDestination results2 = new XdmDestination(); transformer2.Run(results2); Console.WriteLine("1: " + results1.XdmNode.StringValue); Console.WriteLine("2: " + results2.XdmNode.StringValue); } This uses "new XdmAtomicValue(string)". Using WrapExternalObject is wrong - that's where you want to pass an object that will be wrapped for passing to extension functions, rather than being converted to a regular XDM value. I don't know why it failed the way it did, though.

Thanks, no idea how I missed the constructor :/
