Validation of elements does not add a PSVI data
-----------------------------------------------
Key: XERCESJ-1387

Loaded schema ,file schema.xsd :
<?xml version="1.0" encoding="UTF-8"?>
<xs:schema xmlns:xs="http://www.w3.org/2001/XMLSchema";
elementFormDefault="qualified" xmlns="http://www.example.org/schema/";
targetNamespace="http://www.example.org/schema/";>
<xs:element name="root">
<xs:complexType>
<xs:sequence>
<xs:element name="item">
<xs:complexType>
<xs:sequence>
<xs:element name="foo"
type="xs:string"></xs:element>
<xs:element name="bar"
type="xs:string"></xs:element>
</xs:sequence>
</xs:complexType>
</xs:element>
</xs:sequence>
</xs:complexType>
</xs:element>
</xs:schema>
Compile and run commands:
javac -cp .;./xercesImpl.jar ValidationTest.java
java -cp .;./xercesImpl.jar ValidationTest
Result:
ValidationTest start
declaration==null //1
declaration==null //3
declaration==null //4
When the element is other than document element there is no information about
this element declaration. Using document or documentElement to construct
DOMSource and DOMResult makes it works fine.
