I appreciate all input... and really sorry to have missed a clear idea of what i'm in front of at the moment. The thing is this: Having a sale given, I have to create an XML file to send to authorized supplier of certifying (PAC), so there is a clear specification of format (by www.sat.gob.mx/.../cfdv33.xsd). So at the very moment that i'm about to get signed this document, have to get extended info about me (that is the seller), about customer, extended info about items, and then put all inside the dataset and XML-WRITE it, sign locally by SSL and my certificate and encription key, put the digest in a node inside same document and send this file to PAC so it's signed by them and get back the same file with an extra node with info about the signing, at this moment I know the document was authorized (it could be the case that it is rejected!!!), so have to make data permanent and store the signed xml. The XML has info of about just one sale, so it's one header, and several child rows (in my case is really small amount of child records, not more that 10) each item has 2 or three related records. So it's not massive. 2019 law, will force me to make 30 bill documents, each with 1,000s rows, so that _wil_ be really big. The authorities sell us the idea of fiscal system in Mexico is most advanced in the world... not sure, but.... So this is somewhat broader panorama of project at hand. TIA
