Description

This fails with SaxonJS 2.3 but the same XSLT runs OK using the Java version of Saxon. Here is the SaxonJS standard output:

Saxon-JS
2.3

    ==== Watch Variables ====
      doc:     books
    
Transformation failure: TypeError: Cannot read properties of undefined (reading 'Ib')
Cannot read properties of undefined (reading 'Ib')
The terminal process "npx 'xslt3', '-xsl:/Users/philipf/video-demos/init-template/test.xsl', '-it:main', '-o:/Users/philipf/video-demos/init-template/xslt-out/result1.xml'" terminated with exit code: 2.

The input file 'input.xsl' and the stylesheet file 'test.xsl' are attached. The actual command-liine used is in the error message above.

I'm guessing that the xsl:for-each instruction in test.xsl is not setting the context item required by xsl:copy as one would expect.

I think it is the mode="#current" that lets Saxon-JS struggle, use no mode attribute on the apply-templates or mode="#default" as a workaround.

The specification is not very explicit about what the initial value of "current mode" should be when a stylesheet is invoked using call-template invocation. We're setting it to absent, and this causes a failure when apply-templates mode="#current" is used.

Overall, I think the intent is that the current mode should never be null/absent (see §5.3.4 "Clearing the current mode causes the current mode to be set to the default (unnamed) mode." - though that's itself ambiguous since the default mode and the unnamed mode are not the same thing.)

I've changed the code in transform.js so that the current mode in the context is set in the same way for call-template and call-function invocation as for apply-templates invocation, and the test case now passes.
