Discover errors for missing attributes and elements

["Murphy, Eric" <er...@pfc.cfs.nrcan.gc.ca>]

I am trying to get the name of attributes and elements that are missing when
validating an xml tree.  If an attribute has a bad value this is easily done
from the XmlError object:

// the cursor is positioned where the error occured and the attribute name
is returned
   cursor = error.getCursorLocation();        
   attributeName = cursor.getName();

If the attribute is required but simply not there it is easy to get the name
embedded in an error message:

	error.getMessage() prints out - Expected attribute:  file_name

I would rather not count on parsing the error message to get the name of the
missing attribute value - file_name.  If the fromat fo the error message
changes the code will break. Any suggestions?
