	XML-Data-Block-Parser Implementation
	by Loren Petrich,
	September 14, 2000
	
Oct 24, 2001 (Loren Petrich):
	Added "SourceName" field for indicating source of XML data for easier debugging

Jan 25, 2002 (Br'fin (Jeremy Parsons)):
	Added CopyCStringToPascal for Carbon, in place of c2pstr

April 15, 2003 (Woody Zenfell):
        Made XML interpretation error reporting less obnoxious (uses Logging)
