The XML Extensions deployment system consists of the following files: 
	 
 
	  
		- xmlif COBOL-callable subprogram library (cobxmlext.dll on Windows and 
		  cobxmlext.so on UNIX). For more information, see 
		  XML Extensions Statements Reference. 
		
- For Windows: 
		  MSXML 6.0, the Microsoft XML parser, schema processor, and XSLT transformation processor (msxml6.dll, msxml4a.dll, and msxml4r.dll). 
		
- For UNIX: 
		  XSLT transformation processor libraries (libxml and libxslt, respectively) and the XML parser. Currently, these libraries are linked into the 
		  cobmlext.so files and do not need to be installed separately.
