Hi James, All,
I didn't see an example with startingLoc less than 1.
However, one document down in the xpath-functions one there is clarity.
https://www.w3.org/TR/xpath-functions/#func-substring
And I should have looked at that first.
I think this means edge case non conformance bugs in rdf4j and virtuoso.
I will propose a fix for it in rdf4j and file a bug for it for virtuoso.
i.e. SUBSTR("ABC", 0, 2)
should return "A" because only for position 1
does fn:round(0) <= 1 and 1 < fn:round(0) + fn:round(2) hold
Regards,
Jerven

Hi All,
Cross posting as this seems to be a question of spec implementation
and I am not sure what the correct answer is supposed to be.
look at the examples in the document which you referenced.
best regards, from berlin,
