Summary: NullPointerException when parsing an instance that has a schema with inheritable attribute
Key: XERCESJ-1583

If I parse the instance.xml file using the following java code, I get an NullPointerException. I tested on the xml-schema-1.1-dev branch.
-----------Java code-----------------------
XMLReader parser = new org.apache.xerces.parsers.SAXParser();
parser.setFeature(Constants.XERCES_FEATURE_PREFIX + Constants.SCHEMA_VALIDATION_FEATURE, true);
parser.parse("file:/C:/instance.xml");

Mukul Gandhi commented on XERCESJ-1583:
---------------------------------------
If I understand correctly, Xerces currently doesn't expose XSD 1.1 validation other than via JAXP APIs. Therefore, any attempt to do XSD 1.1 validation with Xerces other than via JAXP (for e.g, as used in your example in this bug report) is currently not implemented and unsupported in Xerces.

[jira] [Commented] (XERCESJ-1583) NullPointerException when parsing
an instance that has a schema with inheritable attribute
Posted by "Michael Glavassevich (JIRA)" <xe...@xml.apache.org>.
[ https://issues.apache.org/jira/browse/XERCESJ-1583?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13447508#comment-13447508 ]
Michael Glavassevich commented on XERCESJ-1583:
-----------------------------------------------
Mukul, the problem is that Xerces is throwing an NPE in XSD 1.0 mode. This is an invalid XSD 1.0 schema document. We should report an error, but Xerces shouldn't throw an NPE.
Looking at the code I can see that this is another place where we're missing an explicit check against XSDHandler.fSchemaVersion.
