Description

I thought any (experimental) XPath 4.0, XQuery 4.0 and XSLT 4.0 support is restricted to PE and EE but somehow I find that both Saxon HE 11.5 and 12.2 from the command line execute XQuery 4.0 code using the -> compact function syntax just fine e.g.

xquery version "4.0";

for-each-pair((1 to 5), (1 to 5) => reverse(), ->($a, $b) {$a + $b})
PS C:\Users\marti\OneDrive\Documents\XQuery\XQuery4\thin-arrow-operator> type .\thin-arrow-function1.xq
xquery version "4.0";

for-each-pair((1 to 5), (1 to 5) => reverse(), ->($a, $b) {$a + $b})
PS C:\Users\marti\OneDrive\Documents\XQuery\XQuery4\thin-arrow-operator> java -cp 'C:\Program Files\Saxonica\SaxonHE11-5J\saxon-he-11.5.jar' net.sf.saxon.Query -t thin-arrow-function1.xq

Undocumented or unintended?

Undocumented or unintended?

“Yes.”

That’s definitely unintended. I’ve got a couple of open issues for
places where I think HE is doing things that should only be available in
PE and EE. I’d expect those issues to be fixed in a future release, but
chasing them down isn’t my highest priority. :-)

Be seeing you,
norm

Yes, the checking is a little ad-hoc; the checking for a license file is present on some paths and not others. Also, some features are implemented in code that is present in com.saxonica code which is excluded from the HE product, other features are implemented in shared code.

Partially fixed.
