  When JAXP 1.1 method org.w3c.dom.Element.setAttributeNodeNS(Attr newAttr) is used
to add a new attribute to the element which has an attribute with same local name
and namespace URI, it returns null instead of replaced Attr node (See test.java
below) as described in definition of the method in p. 1.2 "Fundamental Interfaces"
of DOM Level 2 Core
(http://www.w3.org/TR/2000/PR-DOM-Level-2-Core-20000927/core.html#ID-745549614).

" setAttributeNodeNS introduced in DOM Level 2
       Adds a new attribute. If an attribute with that local name and that namespace
       URI is already present in the element, it is replaced by the new one.
       HTML-only DOM implementations do not need to implement this method.
       
       Parameters
       newAttr of type Attr
           The Attr node to add to the attribute list.
       Return Value
           Attr
           If the newAttr attribute replaces an existing attribute with the same
           local name and namespace URI, the replaced Attr node is returned,
           otherwise null is returned. "

This bug is found in builds jaxp-1.1ea-b07, jaxp-1.1ea-b08, jaxp-1.1ea-b09,
jaxp-1.1ea2-b10, jaxp-1.1ea2-b11, jaxp-1.1ea2-b12, jaxp-1.1ea2-b13, jaxp-1.1ea2-b14
and affects the new test in TCK JAXP 1.1
