Major Description
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:
<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>
Would result in the following trace
<Element name='a'><SpecifiedLengthExplicitParser><a parser='StringOfSpecifiedLengthParser' /></SpecifiedLengthExplicitParser><AssertExpressionEvaluationParser/></Element>
rather than
<Element name='a'><SpecifiedLengthExplicitParser><a parser='Binary*SpecifiedLengthParser' /></SpecifiedLengthExplicitParser><AssertExpressionEvaluationParser/></Element>
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.
