Brandon Sloane created DAFFODIL-2211:
----------------------------------------
Summary: Poor handling when dfdlx:repType is a built-in xsd type
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
Fix For: 2.5.0
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!
