If we enabled "JDK language assertions" (not XSD 1.1 assertions!), then Xerces's XPath 2.0 engine might result in inconsistent evaluation results in certain cases -- as you've provided one of the evidences. This is due to the fact that, the original authors of PsychoPath XPath 2.0 engine (which is used by Xerces), have used the "JDK assertions" idiom much within their product. We (i.e Xerces team) after inheriting the original XPath 2.0 code base from the original PsychoPath engine contributors haven't touched much the "JDK assertions" parts of the PsychoPath XPath 2.0 engine -- and this manifests in JDK errors in certain cases, as per also your evidence. It is adviced, that Xerces XSD 1.1 CTA implementation when working with full XPath 2.0 mode or using <assert>/<assertion>, must not use "JDK assertions" enabled. > The other error deals when handling xs:ID attributes, when you ask the > source validator to run the query multiple times: > > java -cp $CLASSPATH jaxp.SourceValidator -x 2 -fx -xsd11 -a simple.xsd -i > simple.xml > > I get the following: > > [Error] simple.xml:2:46: cvc-id.2: There are multiple occurrences of ID > value 'id29299'. > [Error] simple.xml:2:46: cvc-attribute.3: The value 'id29299' of attribute > 'id' on element 'simple' is not valid with respect to its type, 'ID'. > [Error] simple.xml:3:45: cvc-id.2: There are multiple occurrences of ID > value 'id29300'. > [Error] simple.xml:3:45: cvc-attribute.3: The value 'id29300' of attribute > 'id' on element 'simple' is not valid with respect to its type, 'ID'. > simple.xml: 115/2=57.5 ms I feel, this may be a bug with jaxp.SourceValidator sample, since it isn't evaluating this validation episode correctly when iterative execution is asked for (but for singleton execution, I can see that result of XSD validation in this case is correct). But we need to investigate this issue further, to conclude that what is exactly wrong. -- Regards, Mukul Gandhi --------------------------------------------------------------------- To unsubscribe, e-mail: j-users-unsubscr...@xerces.apache.org For additional commands, e-mail: j-users-h...@xerces.apache.org
