W3C's role in making the Recommendation is to draw attention to the specification and to promote its widespread deployment.DB2 9.7 APAR Fix list contains list of APARs shipped for each fix pack in DB2 Version 9.7 for Linux, UNIX and Windows products.It provides a set of operations that walk this tree and apply predicates and node-test functions.
As of March 14, 2008, the XQuery Update Facility specification has become a "Candidate Recommendation", which means it is now pretty stable. The answer seems obvious, yet after all the XQuery language itself - or its cousin XSLT2 - is powerful enough to write any transformation of an XML tree.
DB2 10.5 APAR Fix list contains list of APARs shipped for each fix pack in DB2 Version 10.5 for Linux, UNIX and Windows products.
The Severity column value of 1 is high and 4 is low.
Therefore a simple "store" or "put" function, applied to the result of such transformation, could seem sufficient to achieve any kind of database update operation. In practice this would be neither very natural, convenient, nor very efficient (such an approach requires storing back the whole document and makes optimizing very difficult).
So as we will see the little complexity added by XQuery Update seems quite worth the effort.
