Fix Version/s: 2.12.0
> NPE when collecting the asserts from a base type

> Key: XERCESJ-1610
> URL: https://issues.apache.org/jira/browse/XERCESJ-1610
> Project: Xerces2-J
> Issue Type: Bug
> Components: XML Schema 1.1 Structures
> Affects Versions: 2.11.0
> Reporter: Octavian Nadolu
> Assignee: Mukul Gandhi
> Fix For: 2.12.0

>
> When I validate the following schema I get a NullPointerException. The
> exception occurs because it tries to collect the assertions from a base type,
> and the base type does not have a name because is anonymous.
> I tested on the xml-schema-1.1-dev branch.
