I noticed that if you define a format with an error in a property (I.e.
calendarTimeZone="notValid"), and you reference the format in an element
in another schema file, the Error traceback provides the element that uses
the format as the context, and the filename that contains the definition
of the element, not the definition of the incorrect format itself.

Here is the Schema Definition Error (note that it's also not getting propagated
correctly to the 'red text' area of the output:

In the file specified we have the element declaration:

<xs:element name="date2" type="xs:date" dfdl:ref="b06:dateTZtypo"
dfdl:calendarPattern="MM-dd-yyyy" dfdl:calendarPatternKind="explicit"/>

But the offending formatting is in
daffodil-test/src/test/resources/edu/illinois/ncsa/daffodil/section06/names
paces/subfolder/multi_C_06_nons.dfdl.xsd:

<dfdl:defineFormat name="dateTZtypo">
<dfdl:format ref="dateNoTZ" calendarTimeZone="5 o'clock somewhere"/>
</dfdl:defineFormat>

It is returning a filename (though no line number), but
it's just the location of the element, not the formatting itself.
