> This is part of a large schema project. So link access to the schema project will follow in a different comment.
> But a short synopsis is when the repType of an element in a binary data format is an unsignedlong, the repType is ignored in favor of treating the element like a string type.
> For example:
> {code:xml}
>
> <xs:element name="a" type="tns:jobEnum"/>
> <simpleType name="jobEnum" dfdlx:repType="xs:enum4">
> <restriction base="xs:string">
> <enumeration value="CTO" dfdlx:repValues="1"/>
> <enumeration value="MANAGER" dfdlx:repValues="2"/>
> <enumeration value="TEAM_LEAD" dfdlx:repValues="3"/>
> </restriction>
> </simpleType>
> <xs:simpleType name="enum4" dfdl:length="4" dfdl:lengthKind="explicit" dfld:lengthUnit="bits">
> <xs:restriction base="xs:unsignedLong"/>
> </xs:simpleType>
> {code}
>
> Would result in the following trace
> {code:xml}
> <Element name='a'><SpecifiedLengthExplicitParser><a parser='StringOfSpecifiedLengthParser' /></SpecifiedLengthExplicitParser><AssertExpressionEvaluationParser/></Element>
> {code}
> rather than
> {code:xml}
> <Element name='a'><SpecifiedLengthExplicitParser><a parser='Binary*SpecifiedLengthParser' /></SpecifiedLengthExplicitParser><AssertExpressionEvaluationParser/></Element>
> {code}
> Unfortunately the workaround mentioned in https://issues.apache.org/jira/browse/DAFFODIL-2596?focusedCommentId=17475017&page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel#comment-17475017, won't work for our usecase because the data is binary and has very specific bit length requirements.
