Michael Glavassevich resolved XERCESJ-1387.
-------------------------------------------
Resolution: Invalid
You're not getting PSVI because you're starting validation from an element
which doesn't have a global element declaration in the schema. The only global
element declaration in your schema is "root" and so that is the only valid
element that you can pass in as an element node to validate(). If the error
handler in your test didn't ignore errors you would see that:
org.xml.sax.SAXParseException: cvc-elt.1.a: Cannot find the declaration of
element 'item'.

If you want to start validation from other parts in the document you would need
to modify your schema so that the other element declarations are also global.

> 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.
