  Method org.w3c.dom.Node.cloneNode() incorrectly clones an Attr the Attr node with
its children when the node is cloned with parameter deep=false. The method returns
duplicate node with children.
  The testcase consists of the steps (see test.java below):
  
  1. The Attr node is created by Document.createAttribute();
  2. The Text node is appended to it.
  3. The created node is cloned with deep=false.

  The DOM Level 2 spec
(http://www.w3.org/TR/2000/REC-DOM-Level-2-Core-20001113/core.html#ID-1950641247) does
not describe how the Attr node with children is cloned. This implies that the Attr
node with children is cloned the same way as described for general case. Namely,
children cloning depends on the value of parameter 'deep'.
  So the duplicate node should not have any children. Also the duplicate node should
have an empty value because the value of cloned Attr node had not explicitly set.

  This bug is found in jaxp-1.2.0-beta-b06-06_feb_2002 and affects the test in the
JAXP 1.2 TCK.
