> Key: DAFFODIL-2211
> URL: https://issues.apache.org/jira/browse/DAFFODIL-2211
> Project: Daffodil
> Issue Type: Bug
> Components: Front End
> Affects Versions: 2.4.0
> Reporter: Brandon Sloane
> Priority: Minor
> Attachments: b.dfdl.xsd, c.dfdl.xsd
>
>
> Attached are two cases, both of which contain:
> {quote}<xs:simpleType name="SomeEnumType" dfdlx:repType="xs:unsignedByte">
> <xs:restriction base="xs:unsignedShort">
> <xs:enumeration value="55" dfdlx:repValues="0" />
> <xs:enumeration value="56" dfdlx:repValues="1" />
> <xs:enumeration value="57" dfdlx:repValues="2" />
> </xs:restriction>
> </xs:simpleType>
> {quote}
> In some cases this could potentially make sense (eg. when the document format is such that unsignedByte is automatically 8 bits), but we probably want to disallow this entirely.
> In b.dfdl.xsd, the entire document is using representation='text'. This fails with a somewhat reasonable error:
> {quote}[error] Schema Definition Error: Type UnsignedShort with dfdl:representation='text' cannot have dfdl:lengthKind='implicit'
> Schema context: element reference tns:a Location line 1 in file:/home/bsloane/Documents/incubator-daffodil/test/test/b.dfdl.xsd
> [error] Schema Definition Error: Type UnsignedShort cannot have lengthKind='implicit' when representation='text'
> Schema context: element reference tns:a Location line 1 in file:/home/bsloane/Documents/incubator-daffodil/test/test/b.dfdl.xsd
> {quote}
> in c.dfdl.xsd, the document is useing representation='binary', and fails with an unhandled exception:
> {quote}!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!! An unexpected exception occurred. This is a bug! !!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!
