Can you please post a test case, that demonstrates that with our XSD 1.1 codebase on SVN branch, the Schema (javax.xml.validation.Schema) object is not thread safe?

>          Issue Type: Bug
>          Components: XML Schema 1.1 Structures
>    Affects Versions: 2.12.0

>            Reporter: Stephan Trebels
>            Priority: Critical

> The XSD 1.1 validation code uses eclipse webtools xpath to validate assertions. The PsychoPath XPath 2.0 engine has a bug in ResultSequenceFactory, which invalidates correct execution in all parallel invocation of XSD 1.1 validation. 
> This issue affects completely unrelated schemas and input XML, as long as both use assertions. The effect is a lot of spurious assert violations.  The issue is visible even if only two threads are used in parallel.
