Oddly, if I remember to change the @version on the XSLT stylesheet to 4
and the engine in the transformation scenarion to Saxon EE 13, hash()
works in the XSLT stylesheet I want it for, while in the XPath/XQuery
builder, your example does not work. 

I get told there isn't a 1-argument hash function. Which is a surprise.
The example works fine in BaseX, so I'm going to presume there's no
syntax issue introduced by a helpful mail transport agent or my
ineptitude.

I haven't gone and adjusted anything in oXygen about making EE 13 the
default for XQuery, which would be my first guess as to why selecting it
as the engine for the query isn't efficacious. (oXygen has been
restarted.)

I am using the latest oXygen 28.1, so hopefully that's not it.

But, it works in XSLT, so success!

Thank you!
