Hello DFDL community,
My input contain a Length field that must be of length 4. Here is a sample
input:
.../ 101/...
There is a space prior to 101, although it might be hard to see it. So that
field is of length 4.
The Length field could be nil; a dash is the nil value.
I figured this is the way to declare the Length element:
<xs:element name="Length"
nillable="true"
type="xs:int"
dfdl:lengthKind="explicit" dfdl:length="4"
dfdl:lengthUnits="characters"
dfdl:nilValue="%WSP*;-%WSP*;"
dfdl:textNumberPadCharacter="%SP;"
dfdl:textNumberJustification="right"/>
But Daffodil gives these warning messages:
Warning: DFDL property was ignored: textNumberJustification="right"
Warning: DFDL property was ignored: textNumberPadCharacter="%SP;"
How come I get those warnings?
Anyway, I removed those two properties and then Daffodil simply refused to
parse the Length field. How come? What is the right way to do this?

P.S. It would be nice if Daffodil, when outputting a warning message, gave a
brief explanation of why. For example, why is textNumberJustification="right"
ignored?
