Description

While testing whether SaxonJS supports the simplified stylesheet module syntax I found that it seems to work when using xslt3 from the command line but when I try to use fn:transform from the XPath API (i.e. SaxonJS.XPath.evaluate) I get an error XTTE0590 in XSLT-SEF-compiler.xsl: "Required cardinality of value of parameter $stylesheet-base-uri is exactly one; supplied value is empty".

Sample code:

const SaxonJS = require('saxon-js');

const xml = `<expense-report>
  <total>2500</total>
</expense-report>`;

const xslt = `<html xsl:version="3.0"
      xmlns:xsl="http://www.w3.org/1999/XSL/Transform"
      xmlns="http://www.w3.org/1999/xhtml">
  <head>
    <title>Expense Report Summary</title>
  </head>
  <body>
    <p>Total Amount: <xsl:value-of select="expense-report/total"/></p>
  </body>
</html>`;

const result = SaxonJS.XPath.evaluate(`
  transform(map {
    'stylesheet-text' : $xslt,
    'source-node' : parse-xml($xml),
    'delivery-format' : 'serialized'
  })?output
`,
  null,
  {  params : { xml : xml , xslt : xslt } }
);

console.log(result);

Complete error output:

I don't have to set a stylesheet base URI or change anything in the JavaScript code, as soon as I provide a normal stylesheet module as xslt the code works fine. So somehow the simplified stylesheet module does not work when used with the XPath API and fn:transform as shown above.

This is certainly an interesting one. I'm not (personally) a huge fan of simplified stylesheet modules, but they ought to work. And the reason why they don't is a very mysterious case where a tunnel parameter goes missing. It doesn't look like there's any reason why it shouldn't work. The XX compiler is prepared for the case and does the right thing, but then, like I said, the tunnel parameter for $stylesheet-base-uri goes AWOL.

This turned out to be a simple error in the way the $stylesheet-base-uri is being used as a tunnel parameter in the XX compiler.
