Hmmm. Steve Lawrence is right. XML normalizes CR to LF.
But I'm wondering if you just need to use dfdl:outputNewLine="%CR;%LF;"
property. This would make the output line endings into CRLF when unparsing.
This is not the default setting for this property. By default this property
gets its value from the variable $dfdl:outputNewLine which has default value of
%LF;.

Hello DFDL community,
My input file consists of a prolog of known format and a payload surrounded by
parentheses. The payload consists of a series of text fields separated by
hyphens. In some cases, the hyphen can be preceded by a new line, which can be
a carriage return or CRLF combination.
Here is a sample input file; I show it in a hex editor so you can see that some
hyphens are preceded by CRLF and others by just a CR.

Here is my DFDL schema:
<xs:element name="input">
<xs:complexType>
<xs:sequence>
<xs:element name="prolog" type="xs:string" dfdl:terminator="%NL;" />
<xs:element name="payload" dfdl:initiator="(" dfdl:terminator=")">
<xs:complexType>
<xs:sequence dfdl:separator="-"
dfdl:separatorPosition="infix">
<xs:element name="field" type="xs:string"
maxOccurs="unbounded" />
</xs:sequence>
</xs:complexType>
</xs:element>
</xs:sequence>
</xs:complexType>
</xs:element>
When I parse the input file using the DFDL schema, I get this XML:
<input>
<prolog>PROLOG</prolog>
<payload>
<field>A</field>
<field>B</field>
<field>C
</field>
<field>D</field>
<field>E
</field>
<field>F</field>
</payload>
</input>
That’s perfect.
When I unparse the XML I get this (please note the bug (?) described in yellow):
