Problem solved.... and I've been hit by this in the debugger... The reason is that xsl:evaluate on SaxonJS2 is more conformal than it was on JS1. In particular it implements https://www.w3.org/TR/xslt-30/#evaluate-static-context more properly in that user functions are only visible if their visibility is not hidden or private.
In this case the default visibility rules, in the absence of an @visibility or any xsl:expose declarations, appears to be private, hence xsl:evaluate doesn't see it. The solution should be to mark these functions with @visibility="public". It would be simplest for you to try that, rather than me have to download the files.
Note that this, if correct, would need to apply to any function being referenced by xsl:evaluate evaluation.

- Status changed from In Progress to Rejected
As suggested I have added the attribute visibility="public" to the functions. Saxon-Forms works great on Saxon-JS2. Closing the bug as rejected.
