There are some known issues related to how Daffodil incorrectly implements separatorSupressionPolicy. However, I'm not sure if those are the cause of the behavior you're seeing, since I don't think separatorSuppressionPolicy really works like that. Mike knows more about those issues and SSP.
That said, if you want to require a trailing newline, you can change the dfdl:separatorPosition for your NL sequence from "infix" to "postfix". You can think of infix and postfix as the same thing except that with postfix the last instance is followed by the separator, whereas with infix the last instance is not followed by the separator. - Steve On 11/23/18 11:27 AM, Costello, Roger L. wrote: > Hello DFDL community, > > I have a text format that contains a sequence of rows separated by newline. > Each > row contains a sequence of strings separated by colon. > > Suppose I do not want to allow the last row to contain a newline.
