The dfdl:textNumberJustification property applies to the element regardless. When parsing and nilLiteralValue, trimming takes place before the value is examined for nil value. (That rule enables a nilValue like 'NIL' to be used in scope for many fixed length elements regardless of length).

Subject: [DFDL-WG] clarification: pad/trim and nilKind='literalValue' for text numeric elements
Sent by: dfdl-wg-bounces@ogf.org

Consider:

<element name="e" type="xs:int" nillable="true"
dfdl:lengthKind="explicit" dfdl:length="4"
dfdl:nilValue="-"
dfdl:textPadChar="%SP;"
dfdl:textNumberJustification="right"
dfdl:representation="text"/>

Is a nil justified on the right, or are only number values justified on the right?

That is, will [- ] be interpreted as nil, or only [ -]

A literal nil value is effectively textual syntax, and has nothing to do with whether the field is number or string,

so one might legitimately say that textStringJustification applies to it.

But then again....
