I have been trying to run those tests marked as is-XPath2 = 'true' in the XQTS catalog with an XPath 2.0 processor. Before parsing, I remove variable declarations (and other XQuery prolog statements) between insert-start and insert-end comments. Unforunately the is-XPath2 flag does not always appear to be correct. There are 4859 tests marked as is-XPath2 = 'false' which appear to give the same results as if they were run with an XQuery 1.0 processor. There are also 694 tests which are marked as is-XPath2 = 'true' which don't give the same result, details of which are given below. Using an XPath 2.0 processor, the following queries give a result different from that given by an XQuery 1.0 processor due to the differences in the StringLiteral grammar between the two languages.

I have started work on reviewing the is-XPath2 attribute on the tests, but there are some cases I where I am not sure what the correct value is. consider fn-union-node-args-015: (: insert-start :) declare namespace atomic="http://www.w3.org/XQueryTest"; declare variable $input-context external; (: insert-end :) ($input-context/atomic:root/atomic:integer) union ($input-context/atomic:root/atomic:integer) If we merely strip the prolog then this is a valid XPath2 expression, but in order to evaluate the query then the namespace declaration must be added as an in-scope namespace. The three options I can see are: 1. Set is-XPath2 to false 2. Require an XPath2 test harness to parse the (XQuery) prolog that appears between (: insert-start :) and (: insert-end :) - Is this a resonable burden to place on an XPath2 test runner? 3. Add the required namespace declarations and so on to the catalog. (This would just be duplicating the information - will this cause more trouble than it is worth? (Is it even valid to have a namespace declaration in the insert-start/insert-end section? - this is not mentioned in the guidelines for running the test suite.) The other case that I am unsure how to mark up is the tests that are valid XPath2 but return different results, for example literals056 ("&"). I would argue that this is an important test and so should be marked as is-XPath2. However there is no standard way of recording these alternate results. I would suggest adding the is-XPath2 attribute to output-file as well and mark it up as such: <test-case is-XPath2="true" name="Literals056" FilePath="Expressions/PrimaryExpr/Literals/" scenario="standard" Creator="Mike Rorke"> <description>Test for string literal containing the predefined entity reference '&amp;'.</description> <spec-citation spec="XQuery" section-number="3.1.1" section-title="Literals" section-pointer="id-literals"/> <query name="Literals056" date="2005-02-03"/> <input-file role="principal-data" variable="input-context">emptydoc</input-file> <output-file is-XPath2="false" role="principal" compare="Text">Literals056.txt</output-file> <output-file is-XPath2="true" role="principal" compare="Text">Literals056-XPath.txt</output-file> </test-case> Does anyone else have an opinion on which resolution is best?
I have updated all the is-XPath2 attributes, marking tests as true that are valid XPath 2.0 tests (when stripping the content between (: insert-start :) and (: insert-end :)) and that give the same result under XPath and XQuery. The tests that could be made XPath compatible have for the moment been marked as false. I am marking this bug closed.
abbreviatedSyntax-26, which includes a 'let' expression is incorrectly marked as is-XPath2 = "true".
I have made this change
Confixed fixed.
