Generate PDF/A-3 documents from Pega
We are trying to generate PDF/A format documents in our application which have embedded attachments. OOTB activity HTMLToPDF supports a parameter pyPDFGeneratePDFA to generate PDF/A format documents but it uses quite old PD4ML library for this. The generated document is in PDF/A-1 version and that doesn't support embedded attachments.
Is there a way to generate PDF/A-3 documents from Pega which support embedded attachments. Is any enhancement being done in this area of Pega platform in coming releases
