Thanks Steve. So if I specify these properties

> dfdl:length="9"
> dfdl:lengthUnits="characters"
on an element with complexType, does that implicitly mean "If the element's
value has a length of less than 9, then the value must be left-justified and
must be padded on the right with spaces? That seems to be how Daffodil is
behaving.

textStringJustification and textStringPadCharacter?
Padding/justification only applies to simple xs:string types. They do
not apply to complex types. An alternative would be to model the extra
spaces as a terminator of your MilitaryDayTime element, e.g.
<xs:element name="MilitaryDayTime"
dfdl:lengthKind="implicit"
dfdl:terminator="%SP;%SP;">
