Michael Beckerle commented on DAFFODIL-1616:
--------------------------------------------
Don't have an obvious way to reproduce the user's error, but this property is
only needed, and should only be looked for under a very narrow set of
circumstances.
type is simple, but not string nor hexBinary
representation is text
textPadKind is padChar
lengthKind is one of delimited, prefixed, pattern, endOfParent, or explicit
when length is NOT a constant.
When those are all true, then to determine the minimum length (for an
unparser), we use this property.
The code for textOutputMinLength now simply checks all the above.
Tests of the IBM DFDL Cross-test rig run IBM samples that do not have
textOutputMinLength defined. These tests used to fail for lack of this property
(and we modifed the schemas to have it). Now the schemas are modified to NOT
have the property and these tests work:
They are in the test class TestIBMDFDLSamples.test_company1() and
test_company1SelfContained().
That cross test rig was created in github and can be cloned via git clone
[email protected]:OpenDFDL/ibmDFDLCrossTester.git
It may, however, move elsewhere... perhaps to DFDLSchemas?

> (Note that I have been using the very same DFDL definition when running the
> TDML test that I have prepared)
> I checked the docs and, in section 13.2, it says that 'textOutputMinLength'
> is 'common to all simple types with text representation'; in my DFDL, there
> are _no_ fields with such representation, I use only (unsigned) integers and
> bit flags.
> I checked the line in error message 'Schema context': it looks like this:
> <xs:element name="CAT" type="adatp-35:ushort8"/>
> while the 'adatp-35:ushort8' type is defined as follows:
> <xs:simpleType name="ushort8" dfdl:lengthKind="explicit"
> dfdl:length="1" dfdl:lengthUnits="bytes">
> <xs:restriction base="xs:unsignedInt"/>
> </xs:simpleType>
> Any help would be greatly appreciated!
