xml stream handling is inconsistent
-----------------------------------

                 Key: TEIID-917
                 URL: https://jira.jboss.org/jira/browse/TEIID-917
             Project: Teiid
          Issue Type: Bug
          Components: Common
    Affects Versions: 6.0.0
            Reporter: Steven Hawkins
            Assignee: Steven Hawkins
             Fix For: 7.0


Our SQLXMLImpl allows for a variety of source types - such as a streamsource coming from the xml source connector.  However if the resulting SQLXML is used by the client (and not immediately consumed by something like XQuery) then the stream can only be read once.  Also all of the conversion routines in the XMLTranslator logic (and in the xml document stylesheet application) are based upon full materialization.  This may lead to memory problems.  In general our SQLXMLImpl should be backed by a string if small and a (temp) file if large.  Conversions from DOM and SAX sources would also need to create temp files to protect memory and allow for multiple reads respectively.
