Saxon.Api.StaticError: 'xsl:import-schema requires Saxon-EE' with .net API

Question

I've downloaded the .NET Saxon API. I've compiled and run the EE sample application. Some of it required the license to be present, and I have a license file, which seemed to make it work.

I wanted to use xsl:import-schema in my xslt, and this xslt works in the Oxygen editor (which has its own EE license).

If I take the simple xslt example from the saxon sample and then attempt to get it to compile my xslt with the import-schema instruction I get:

    Saxon.Api.StaticError: 'xsl:import-schema requires Saxon-EE'

That is true. However I am already explicitly referencing the Saxon EE library, so that shouldn't be an issue (see below for a clue):

Here's my code:

            var samplesDir = new Uri(AppDomain.CurrentDomain.BaseDirectory);
            String dir = samplesDir.LocalPath;
            String sourceFile = Path.Combine(dir,"po.xml");
            String styleFile = Path.Combine(dir,"po.xsl");

            // Create a Processor instance.
            Processor processor = new Processor();

            // Load the source document
            DocumentBuilder builder = processor.NewDocumentBuilder();
            builder.BaseUri = new Uri(sourceFile);

            XdmNode input = builder.Build(File.OpenRead(sourceFile));

            XsltCompiler compiler = processor.NewXsltCompiler();
            //compiler.SchemaAware = true;
            compiler.BaseUri = new Uri(styleFile);
            // fails on next line
            Xslt30Transformer transformer = compiler.Compile(File.OpenRead(styleFile)).Load30();

            // Set the root node of the source document to be the global context item
            transformer.GlobalContextItem = input;

            // Create a serializer, with output to the standard output stream
            Serializer serializer = processor.NewSerializer();
            serializer.SetOutputWriter(Console.Out);

            // Transform the source XML and serialize the result document
            transformer.ApplyTemplates(input, serializer);

Note that if I comment out the explicit setting to set the SchemaAware setting to true, it says:

    net.sf.saxon.trans.LicenseException
      HResult=0x80131500
      Message=Requested feature (schema-aware XSLT) requires Saxon-EE. You are using Saxon-EE software, but the Configuration is an instance of net.sf.saxon.Configuration; to use this feature you need to create an instance of com.saxonica.config.EnterpriseConfiguration

This is a better clue. It's telling me I am using saxon EE, but I need an instance of com.saxonica.config.EnterpriseConfiguration somehow.

Why am I getting this error message?

Answer 1

you need to tell the processor to behave like a licensed copy (seems a bit odd)

        Processor processor = new Processor(true);

Simple, I'd copied an example that didnt need fancy features, but I'll leave this question as it is, just in case someone else has the same issue.
