[~martin.honnen]
As per XPath F&O spec for fn:fold-left function defined here,
https://www.w3.org/TR/xpath-functions-31/#func-fold-left, the supplied function
to fn:fold-left needs to be an XPath inline function expression (i.e, with
syntax function () { ... }). xsl:function cannot be an argument to fn:fold-left.
I haven't verified, but even if Saxon XSL processor supports xsl:function as
well, as an argument to fn:fold-left then that shall be Saxon's own behavior.
> can't pass XSLT defined xsl:function to fold-left: FORG0006 : The third
> argument to function call fn:fold-left is not a function item, or cannot be
> coerced to a function item

> Project: XalanJ2
> Issue Type: Bug
> Security Level: No security risk; visible to anyone(Ordinary problems in
> Xalan projects. Anybody can view the issue.)
> Components: transformation, Xalan, XPath-function
> Affects Versions: The Latest Development Code
> Environment: Java 8, Windows 11

> This is a bug report against the XSLT 3 development branch of Xalan.
> I am trying to pass a function defined in XSLT with xsl:function to the
> higher-order function fold-left but Xalan doesn't seem to support that so
> far, I get " FORG0006 : The third argument to function call fn:fold-left is
> not a function item, or cannot be coerced to a function item".
> An XSLT stylesheet is attached, it can be run against the file
> src/test/resources/fn_fold_left/test1_a.xml in the Xalan branch.
> In my view the function call should work and the result should be e.g.
> {code:xml}
> <?xml version="1.0" encoding="UTF-8"?>
> <result>
> <val1>210</val1>
> <val2>210</val2>
> </result>
> {code}
> I get the same problem with more complex code trying to use the transform
> function, the stylesheet is also attached.
