	That's going to be a problem since the XFA forms generated by those  
products can't (without a LOT of processing) be made PDF/A  
compatible.   The next major release of LiveCycle Forms Server will  
support the creation of PDF/A compliant files, but I can't comment on  
a date for that.

	OK, so you are having it generate "flattened" PDF.  AND that  
software is VERY old!

	You need to manually add the appropriate PDF/A metadata - iText  
won't do it.

	Create a PDF/X-3 file, which has the same graphic requirements.    
However, iText can NOT help you do this to an existing PDF.

	No.
