Hi,

it's indeed possible but it's a real pain to do this.

This message is the content of the Shell PDF, which surrounds every XFA form and will be the only thing a PDF-viewer can display if it doesn't support XFA.

You can use the PDF stream dumper to edit it, but this is really not easy nor a true pleasure.

Here's a sample PDF, where I modified the message a little bit.
