Mike, this was covered by the 2nd half of errata 3.8 as follows:

Clarify what action a DFDL processor should take when it encounters an object that explicitly carries properties that are not relevant to the object as defined.
o        Property not applicable to the object’s DFDL annotation.
        Schema definition error. Example is lengthKind on xs:sequence.
o        Property not applicable because of simple type.
        Warning (optional). Example is calendarPatternKind on xs:string.
o        Property not applicable because of another DFDL property setting.
        Warning (optional). Example is binaryNumberRep when representation is text.
o        Property not applicable because object is local, global or reference.
        Warning (optional). Example is occursCountKind on a global xs:element.        **

**  Excludes inputValueCalc and outputValueCalc which give SDE.

IBM DFDL has a big bunch of checks for the warnings, but we are considering making them an optional feature on performance grounds.

It's hard to search for this. Does anyone recall resolution to this?

If you specify properties that are clearly mismatched e.g., you specify dfdl:occursCountKind on an element that isn't an array, or you specify dfdl:textStringJustification on a number.

Does this generate an error or a warning or nothing?

Obviously this doesn't cause any issue if these properties are in scope or referenced from a format annotation. It's only an issue if they are actually written locally in short or long-form annotations right on the point where the incompatibility resides.
