Yip Ng updated DERBY-1718:
--------------------------

    Attachment: derby1718-trunk-stat01.txt
                derby1718-trunk-diff01.txt

Attaching initial patch derby1718-trunk-diff01.txt for DERBY-1718.  The fix basically implements the Formatable interface for SqlXmlUtil class.  Currently, it writes out the query expression string instead of the XPath object(its serializable I think), and then later recompiles the query once at evaluation time.  The reason behind this is that I don't  want the stored form to be tied to a particular XML implementation.  But I am open if anyone feels that the Xalan XPath object should be serialized instead.  

To run the lang/xml_general.sql and lang/xmlBinding.java, please refer to the instructions in this thread:

http://article.gmane.org/gmane.comp.apache.db.derby.devel/25793

derbylang and the above xml tests passes.  Running derbyall now.  Appreciate if someone can review this patch.  Thanks.
