---------------------------------------
Summary: emptyElementParsePolicy 'treatAsAbsent' not working
properly
Key: DAFFODIL-2826
URL: https://issues.apache.org/jira/browse/DAFFODIL-2826
Project: Daffodil
Issue Type: Bug
Components: Back End
Affects Versions: 3.5.0
Reporter: Mike Beckerle
In either 3.4.0 or 3.5.0-SNAPSHOT the property
dfdlx:emptyElementParsePolicy='treatAsAbsent' does not seem to be working at
least for empty elements of complex type.
{code:java}
<element name="horizontalVisibility" minOccurs="0"
dfdlx:emptyElementParsePolicy="treatAsAbsent">
<complexType>
<sequence>
<element name="visibility" type="w:visibilityType" minOccurs="0"/>
<element name="directionalVariationInVisibility" minOccurs="0">
<complexType>
<choice>
<element name="noDirectionalVariation"
dfdl:initiator="%WSP+;NDV NDV" type="w:zlString"/>
<sequence dfdl:initiator="%WSP+; %ES;">
<element name="minimumVisibility" type="w:uint4"/>
<element name="direction" type="w:directionEnum"/>
</sequence>
</choice>
</complexType>
</element>
</sequence>
</complexType>
</element>
{code}
The enclosing parent element horizontalVisibility is optional. If all content
within it is not present, the property
dfdlx:emptyElementParsePolicy="treatAsAbsent" means that this empty complex
type element should NOT be added to the infoset.
Daffodil does have tests for emptyElementParsePolicy, but perhaps the
complex-type element case is not included?
