> 1. Changed internal code design significantly for Schema 1.1 assertions processing (mainly in validator and evaluation layers. traverser implementation is mostly untouched since 2.11.0 release), involving quite a bit of re-factoring to improve understandability and maintainability of code base.
> 2. Improvements to assertion failure messages. Now assertion facet failure messages are similar to other facet failure messages. Earlier it was not apparent in error messages, that a facet failure with xs:assertion *was from a facet*.
> 3. Improved processing logic for assertion evaluations for simpleType's with variety union. Improvements to updation of memberType PSVI result when assertions are involved for simpleType with variety union.
> 4. Providing an improved PsychoPath XPath 2.0 JAR file.
> 5. It's now (change done post 2.11.0 release) a static error to have xs:assert XPath expressions to begin with / or // (since assert XDM trees are rooted at a parentless element). for e.g /x, //x or a[/x] etc are incorrect assert XPath expressions and would result in a static error. This change requires the new PsychoPath XPath 2.0 JAR.
> 6. If xs:any wildcard has processContents="skip", then that part of XML content tree should be available to relevant assertions. This improvement is done post 2.11.0 release.
> 7. Implemented [failed assertions] PSVI property for "element information items".
