XmiCasSerializer passes null for an attribute's URI and localName
-----------------------------------------------------------------

                 Key: UIMA-1753
                 URL: https://issues.apache.org/jira/browse/UIMA-1753
             Project: UIMA
          Issue Type: Bug
          Components: Core Java Framework
    Affects Versions: 2.3
            Reporter: Greg Holmberg
            Priority: Minor


XmiCasSerializer.XmiCasDocSerializer has this method: 

     private void addAttribute(AttributesImpl attrs, String attrName, String attrValue) { 
         attrs.addAttribute(null, null, attrName, cdataType, attrValue); 
     } 

This causes a NullPointerException in some ContentHandlers (such as those for EXI from Siemens and AgileDelta).

The JavaDoc says to pass an empty String for these parameters when you don't have a good value for them.

So the line should be changed to:

    attrs.addAttribute("", "", attrName, cdataType, attrValue); 

I tested that change with the AgileDelta ContentHandler, and it no longer threw any exceptions.
