Mike, isn’t this an example of a hidden optional element:
<xs:sequence dfdl:hiddenGroupRef="hidden-newline" />
…
<xs:group name="hidden-newline">
<xs:sequence>
<xs:element name="EOL" type="xs:string" minOccurs="0"
dfdl:initiator="%NL;" dfdl:lengthKind="explicit" dfdl:length="0" />
</xs:sequence>
</xs:group>

Nope. You can't have hidden optional elements. It makes no sense. They're
hidden, so they do not exist at the time you start unparsing. Since they are
optional there's nothing to make them come into existence when unparsing. On

Results in this error: dfdl:outputValueCalc cannot be defined on optional
elements.
Is there a way to hide optional elements?
