Olabusayo Kilo commented on DAFFODIL-1842:
------------------------------------------
I'm unable to reproduce this. I have the following and it doesn't complain
about the referencer and referencee having the same properties expressed
directly on them. Does my example look correct?
{code:xml}
<tdml:defineSchema name="PropertySyntaxOverlap">
<xs:include
schemaLocation="/org/apache/daffodil/xsd/DFDLGeneralFormat.dfdl.xsd"/>
<dfdl:format ref="ex:GeneralFormat" lengthKind="delimited"
lengthUnits="bytes" encoding="UTF-8" separator="" initiator=""
terminator="" occursCountKind="parsed" ignoreCase="no"

<xs:element name="e1" type="xs:string" dfdl:lengthUnits="bits"/>

> Project: Daffodil
> Issue Type: Bug
> Components: Front End
> Reporter: Mike Beckerle
> Priority: Major
> Labels: reverify
>
> Element references and the elements they reference cannot have the same
> properties expressed directly on them.
> However, they should be able to override the properties that are inherited
> from the default properties surrounding the global element decl.
> But this error message, from the overlap check, is clearly saying it is
> looking at a SchemaDocument:format annotation, and complaining about overlap
> with it.
> This is not correct. The overlap check should not be considering the default
> format of any schema when determining the overlap.
> TODO: create a public test case that reproduces this error. Right now it came
> up in an FOUO schema that is not publicly available.
