Hello Council, I'm trying to get OxGarage to use XSLT3 so that it can run the new odd2json.xsl that I need for Roma, but I'm running into an error. Saxon 9.8 and over can handle XSLT3. I see that OxGarage already has saxon9he.jar, though I couldn't find out which version it is. I tried switching it with a 9.8 version and run into the same issues. OxGarage source code uses the class XsltTransformer to handle transformations in the class TEIConverter https://github.com/TEIC/oxgarage/blob/master/tei-converter/src/main/java/pl/.... The transformer is then loaded with the method load() https://github.com/TEIC/oxgarage/blob/master/tei-converter/src/main/java/pl/.... I see on the Saxon documentation https://www.saxonica.com/html/documentation/javadoc/net/sf/saxon/s9api/Xslt3... that the way of invoking XSLT3 transformations is by using a different class called Xslt30Transformer, which should also be able to run xslt 1 and 2. So I tried switching XsltTransformer to Xslt30Transformer and using the method load30() instead of load() to load it. When I try to compile with mvn compile, the compilation fails (see error below). I'll keep digging, but I'm wondering if anyone notice else would like to try to reproduce the error and help me figure out what's up. All best and happy new year!
