The xsltproc error is "XPath error: Invalid type"
XMLSpy says "Error in XPath expression, Not a node set"
Both xsltproc and XMLSpy are correct: the expression
not(preceding-sibling::*) does not return a node set but a boolean and
the [...] expression behind it can only be executed on a boolean.
Perhaps when you run it with Saxon you run it as XSLT 2.0 which allows
for a predicate expression on a boolean.
I thought the test expressions are valid v1.0 XSL. Is this not so?
Yes, they are valid.

PS: sending the line number in your post would make it a bit easier to
find what's wrong. Now we have to go through all lines with an XPath.
