I already use unattend.xml on an ISO with the file structure using Source/$OEM$. This tool makes it much faster and I can take it to the client with the SSD "ready"; I just connect it. Anyway, when I replace my autounattend.xml, it doesn't work (I have a question here: is unattend.xml required to be in UTF-8?). I've been using the same one for a long time without any problems. I edit some functions in the default format and it gives errors. I've used https://schneegans.de/ and it fails. That's why I asked for a copy to compare where I'm going wrong. But the link you sent me is custom, and I'll try it and get back to you later. Thank you.
Excuse the English, I'm using Google Translate.
----EDIT----
Reporting that the possible error was UTF-8 BOM (I don't know why Notepad++ changed this and it was in its latest version.)
So far no problems, I've tested with more than 10 computers.
