Changes 2.5.16:
* Fixed container creation so that it honors page size in XmlContainerConfig
* Fix the base-uri of an attribute node when using WholedocContainer storage
* Fixed an assertion failure during query preparation with a recursive user
  defined function
* Fixed an assertion failure when an as-yet unseen URI in used in a query
* Fixed a problem where attribute indexes would not properly be updated if
  there were no element indexes present. This might have a symptom of
  DB_NOTFOUND errors or duplicate index entries for attributes
* Changed the algorithm used to create node IDs during partial update to be
  more efficient and create shorter node IDs in general
* Fixed a problem where deleting the XmlResults object returned by
  XmlValue.getAttributes() might cause an exception when the original
  XmlResults for the XmlValue object was next accessed
* XQuery Update queries will no longer crash when statistics are disabled
* Fixed a bug in document level indexing that could result in index entries
  being deleted inappropriately when a node was deleted
* Fixed fn:doc() to raise an error in all cases if the document does not exist
* Fixed a bug occurring when fn:subsequence() and "order by" were used in
  certain configurations
* Changed XmlResults.asEventWriter(), now only one active XmlEventWriter is
  allowed for an XmlResults object
