+ |                              DESCRIPTION                                   |
+ I expects the following code prints:
+ 
+ xmlns 'urn:x-default1'
+ xmlns:a 'urn:x-unused'
+ xmlns 'urn:x-default2'
+ 
+ or
+ 
+ xmlns 'urn:x-default1'
+ xmlns 'urn:x-default2'
+ xmlns:a 'urn:x-unused'
+ 
+ With Xalan-J 2.2.D10 it prints:
+ 
+ xmlns 'urn:x-default1'
+ xmlns 'urn:x-default2'
+ 
+ There is no xmlns:a node.
+ 
+ 
+ Note: In fact, it should prints five namespace nodes according to XPath 1.0
+ standard.  This bug would be solved if Bugzilla #2650 is fixed completely.
+ But I guess a cause of this bug is not the same as #2650.
+ 
+ This and #2650 cause significant problems for XML-Signature.
