Namespace problems in Xerces-J 1.2.3
I just tried to move from Xerces 1.2.1 to 1.2.3 and found that my documents
that validated fine before no longer do so.
Parsing a bare instance document [1] with a simple schema [2] produces the
following error in Xerces 1.2.3:
org.w3c.dom.DOMException: DOM003 Namespace error
If I remove the <import> element from the schema, the error goes away!
[1] Instance document
=====================
<?xml version="1.0" encoding="UTF-8"?>
<foo xmlns="FooNamespace"
xmlns:xsi="http://www.w3.org/1999/XMLSchema-instance"
xsi:schemaLocation="FooNamespace http://localhost/fooSchema.xsd">
</foo>
[2] Schema
==========
<?xml version="1.0" encoding="UTF-8"?>
<schema xmlns="http://www.w3.org/1999/XMLSchema"
targetNamespace="FooNamespace"
xmlns:xsi="http://www.w3.org/1999/XMLSchema-instance"
xsi:schemaLocation="http://www.w3.org/1999/XMLSchema
http://www.w3.org/1999/XMLSchema.xsd">
<import namespace="http://www.w3.org/XML/1998/namespace"
schemaLocation="http://www.w3.org/2000/04/xml.xsd"/>
<element name="foo">
<complexContent/>
</element>
</schema>

Re: Namespace problems in Xerces-J 1.2.3

Just confirmed with Arnaud, there is a small nit in the DOM implementation
after we applied the default attribute patch from Elena, he will fix that in
a jiffy. maybe he already did that.
Since this will only happen when a dtd has declared a "xmlns" attribute and
this dtd was used by a schema, I would see chances somebody will run into
this is very low, so Thanks to Ramesh, for help unveil this.
