Description

When validating a DOMSource against a schema with attributeFormDefault="unqualified", the validator throws this exception

org.xml.sax.SAXParseException: cvc-complex-type.3.2.2: Attribute 'id' is not allowed to appear in element 'a:person'.

The sample program is pasted below. It shows 3 scenarios. All three use a handbuilt DOM object.

1) testUnqualifiedAttr validates a DOM that is built with an unqualified attribute, the schema has attributeFormDefault="unqualified", this validation fails
2) testQualifiedAttr validates a DOM that is built with a qualified attribute, the schema has attributeFormDefault="qualified", this validation succeeds
3) testQualifiedAttr2 validates a DOM that is built with a qualified attribute, the schema has attributeFormDefault="unqualified", this validation fails
