version 3.1.0:

I suspect this unparse bug w/ Daffodil 2.4 has since been fixed. Parsing is
successful. Details as follows:
daffodil unparse --validate=on -s ... -r ... -o ...

'Miscellanea' referenced above is simply:
<xs:complexType name="Miscellanea">
<xs:sequence>
<xs:element name="value">
<xs:simpleType>
<xs:restriction base="xs:string">
<xs:pattern value=".*"/>
</xs:restriction>
</xs:simpleType>
</xs:element>
</xs:sequence>
</xs:complexType>
It occurs when encountering an empty line/record when using
"dfdl:separatorPosition="postfix"
<xs:complexType name="MU14Type">
<xs:sequence dfdl:separator="%LF;" dfdl:separatorPosition="postfix">
:::
</xs:sequence>
</xs:complexType>
Let me know if more information required.
Thx - Attila
