Problem summary

• XML Canonicalization does not work as expected.
  
  ERROR DESCRIPTION:
  The customer reported that Canonicalization should not remove
  namespace attribute xmlns.
  Expected:
  <my:NodeSetElement
  xmlns:my="mySchema">hello</my:NodeSetElement><my:NodeSetElement
  xmlns:my="mySchema">here goes
  trouble</my:NodeSetElement><my:NodeSetElement
  xmlns:my="mySchema"></my:NodeSetElement>
  but got:
  <my:NodeSetElement>hello</my:NodeSetElement><my:NodeSetElement>h
  ere goes
  trouble</my:NodeSetElement><my:NodeSetElement></my:NodeSetElemen
  t>
  
  In addition to that, we found more issues in C14N
  implementation.
  C14N output does not match the sample output in C14N spec
  (http://www.w3.org/TR/xml-c14n, 3.3 Start and End Tags):
  1, Namespace does not go before other attributes.
  2, Namespace prefixes from original document is not kept.
  3, Superfluous namespace declarations should be removed.
  

Problem conclusion

• Improved IBM C14N implementation:
  1, Keep namespace attribute xmlns in the node.
  2, Namespace goes before other attributes.
  3, Retention of namespace prefixes from original document as
  required by C14N spec.
  4, Elimination of superfluous namespace declarations as required
  by C14N spec.
